	(1) Organization and Basis of Presentation
	Background
	Del Frisco’s Restaurant Group, Inc. (the Company) is incorporated in Delaware as a corporation. Prior to its initial public offering (“IPO”) in 2012, the Company was a wholly owned subsidiary of LSF5 Wagon Holdings, LLC (Wagon), which is a wholly owned subsidiary of LSF5 COI Holdings, LLC (Holdings), which is majority owned by Lone Star Fund V (U.S.), L.P. (the Fund), which is a private investment fund.
	Effective December 13, 2006, the Fund, through Holdings, acquired all of the outstanding capital stock of Lone Star Steakhouse & Saloon, Inc. (Star), through a series of transactions pursuant to an Agreement and Plan of Merger (the Acquisition). Prior to the Acquisition, Star was a public company that owned and operated steakhouse restaurants under four different restaurant brands, which included Lone Star Steakhouse & Saloon (Lone Star), Texas Land & Cattle Steak House (TXLC), Sullivan’s Steakhouse (Sullivan’s), and Del Frisco’s Double Eagle Steak House (Del Frisco’s).
	In connection with the Acquisition, Holdings contributed all of the assets, restaurant operations, trade names, and other intangible assets of its Lone Star and TXLC restaurants to LSF5 Cowboy Holdings, LLC (Casual Dining Companies), which is a wholly owned subsidiary of Holdings. In addition, LS Management, Inc. (LSM), which was previously a wholly owned subsidiary of Star that provided all of the accounting, legal, and other administrative support to all of Star’s restaurants, was contributed to the Casual Dining Companies. Concurrently, the remaining assets and restaurant operations of Star, which primarily included the Del Frisco’s and Sullivan’s restaurants as well as LS Finance, LLC which was previously a wholly owned subsidiary of Star that provided all of the cash management and treasury support to all of Star’s restaurants, were contributed to the Company.
	On July 26, 2012, the Company priced a $75,400 IPO of 5.8 million shares of common stock at $13.00 per share. On July 27, 2012, the Company’s common stock began trading on the NASDAQ Global Select Market under the ticker symbol “DFRG.” Upon the August 1, 2012 closing of the IPO, the Company received net proceeds of $70,122, reflecting $5,278 of underwriting discounts and commissions. Additionally, the Company incurred $3,666 in offering costs that reduced the net proceeds available to additional paid in capital. At the completion of the IPO, an entity controlled by the Fund (together with its affiliates, but excluding the Company and other companies that it or they own or control as a result of their investment activities) owned approximately 18.0 million shares of common stock, or approximately 75.6% of the Company’s outstanding shares.
	Prior to the IPO closing, the Company converted from a limited liability company to a corporation and in connection therewith, the Company’s then-outstanding membership interests were converted into approximately 18.0 million shares of Company common stock (the “Conversion”). All issued and outstanding common stock and per share amounts contained in the financial statements have been retroactively adjusted to reflect the Conversion. As part of the IPO, the Company established its authorized shares at 10,000,000 shares of preferred stock, $0.001 par value per share, and 190,000,000 shares of common stock, $0.001 par value per share. At August 1, 2012, the closing date of the IPO, the Company had a total of approximately 23.8 million common shares issued and outstanding.
	The Company used a portion of the net proceeds from the IPO to repay $61,000 of amounts outstanding under its credit facility on August 1, 2012. In addition, the Company used $3,000 of the net proceeds to make a one-time payment to an affiliate of the Fund in consideration for the termination of an asset advisory agreement upon consummation of the IPO, which is reflected as an operating expense in the consolidated statements of income and comprehensive income. The remainder of the net proceeds will be used for working capital and other general corporate purposes. In conjunction with the repayment of amounts outstanding under the credit facility, the Company wrote-off $1,649 in unamortized debt issuance costs in the third quarter of fiscal 2012.
	On March 7, 2013, a secondary public offering of the Company’s common stock was completed by Lone Star Fund. The selling
	shareholder sold 4,750,000 previously outstanding shares. In addition, on April 10, 2013, the shareholder sold an additional 150,000 shares of common stock to cover over-allotments related to the March 7, 2013 offering. The Company did not receive any proceeds from the offering. The selling shareholder paid all of the underwriting discounts and commissions associated with the sale of the shares; however, the Company incurred $412 in costs and registration expenses related to this offering.
	On July 25, 2013, a secondary public offering of the Company’s common stock was completed by Lone Star Fund. The selling shareholder sold 6,000,000 previously outstanding shares. In addition, on August 6, 2013, the shareholder sold an additional 900,000 shares of common stock to cover over-allotments related to the July 25, 2013 offering. The Company did not receive any proceeds from the offering. The selling shareholder paid all of the underwriting discounts and commissions associated with the sale of the shares; however, the Company incurred $381 in costs and registration expenses related to this offering.
	On December 4, 2013, a secondary public offering of the Company’s common stock was completed by Lone Star Fund. The selling shareholder sold 5,386,667 previously outstanding shares. In addition, on December 6, 2013, the shareholder sold an additional 808,000 shares of common stock to cover over-allotments related to the December 4, 2013 offering. The Company did not receive any proceeds from the offering. The selling shareholder paid all of the underwriting discounts and commissions associated with the sale of the shares; however, the Company incurred $231 in costs and registration expenses related to this offering. At the completion of this offering and the exercise of the underwriters’ over-allotment option, Lone Star Fund did not own any shares of the Company’s outstanding common stock.
	Description of Business
	The Company owns and operates restaurants under the brand names of Del Frisco’s Double Eagle Steak House (“Del Frisco’s”), Sullivan’s Steakhouse (“Sullivan’s”), and Del Frisco’s Grille (“Grille”). As of December 31, 2013 the Company owned and operated 10 Del Frisco’s, 19 Sullivan’s and 11 Grille restaurants. During fiscal 2013, the Company opened Grilles in Houston, Texas, Santa Monica, California, Palm Beach, Florida, Fort Worth, Texas, Chestnut Hill, Massachusetts, and Southlake, Texas.

Summary Of Significant Accounting Policies [Abstract]	'
Summary Of Significant Accounting Policies	'
	(2) Summary of Significant Accounting Policies
	Principles of Consolidation
	The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated.
	Fiscal Year
	The Company operates on a 52- or 53-week fiscal year ending the last Tuesday in December. Fiscal 2011 and 2012 included 52 weeks of operations, while fiscal 2013 included 53 weeks of operations.
	Concentrations
	The Company has certain financial instruments exposed to a concentration of credit risk, which consist primarily of cash and cash equivalents. The Company places cash with high-credit-quality financial institutions, and, at times, such cash may be in excess of the federal depository insurance limit.
	Additionally, the Company purchased a significant amount of total beef purchases from one supplier during fiscal 2011, 2012, and 2013, respectively. Due to the nature of the beef purchases, there are alternative sources of supply available; however, a change in suppliers could potentially cause increased costs.
	Use of Estimates
	The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.
	Cash and Cash Equivalents
	Cash and cash equivalents include currency on hand, demand deposits with banks or other financial institutions, credit card receivables, and short-term investments with maturities of three months or less when purchased. Cash and cash equivalents are carried at cost, which approximates fair value.
	Financial Instruments
	The Company considers the carrying amounts of cash and cash equivalents, short-term investments, receivables and accounts payable to approximate fair value based on the short-term nature of these items. Borrowings available under the credit facility at December 31, 2013 have variable interest rates that reflect currently available terms and conditions for similar debt.
	Inventories
	Inventories, which primarily consist of food and beverages, are valued at the lower of cost, using the first-in, first-out (FIFO) method, or market.
	Property and Equipment
	Property and equipment are stated at cost. Maintenance, repairs, and renewals that do not enhance the value of or increase the lives of the assets are expensed as incurred. Buildings are depreciated using the straight-line method over their estimated useful lives of 20 to 25 years. Leasehold improvements are amortized using the straight-line method over the lesser of the estimated useful lives of the assets of 20 years or the expected term of the lease, including cancelable optional renewal periods when failure to exercise such renewal options would result in an economic penalty to the Company. Furniture, fixtures, and equipment are depreciated using the straight-line method over three to seven years, which are the estimated useful lives of the assets.
	Interest is capitalized in connection with the construction of restaurant facilities. The capitalized interest is recorded as part of the asset to which it relates and is amortized over the asset’s estimated useful life. Capitalized interest was $204,  $104 and $0 for the years ended December 27, 2011, December 25, 2012 and December 31, 2013, respectively.
	Operating Leases
	The Company leases restaurants under operating leases. The majority of the Company’s leases provide for rent escalation clauses, contingent rental expense, and/or tenant improvement allowances.
	Rent expense is recognized on a straight-line basis over the expected term of the lease, which includes cancelable optional renewal periods that are reasonably assured to be exercised and where failure to exercise such renewal options would result in an economic penalty to the Company.
	Certain of the Company’s operating leases contain clauses that provide additional contingent rent based on a percentage of sales greater than certain specified target amounts. The Company recognizes contingent rent expense prior to the achievement of the specified target that triggers the contingent rent, provided achievement of that target is considered probable.
	The Company records tenant improvement allowances and other landlord incentives as a component of deferred rent which is amortized on a straight-line basis over the expected term of the lease.
	Preopening Costs
	Preopening costs, including labor costs, costs of hiring and training personnel, and certain other costs related to opening new restaurants, are expensed when the costs are incurred.
	Goodwill and Other Intangible Assets
	The Company’s intangible assets primarily include goodwill, trade names, and licensing agreements, arising from the 2006 Acquisition. The Company’s trade names include “Del Frisco’s Double Eagle Steak House” and “Sullivan’s Steakhouse,” both of which have indefinite lives and, accordingly, are not subject to amortization. The trade names are used in the advertising and marketing of the restaurants and are widely recognized and accepted by consumers in their respective markets for providing its customers an enjoyable fine-dining experience. Goodwill represents the excess of costs over the fair value of the net assets acquired.
	Goodwill and intangible assets that have indefinite useful lives are not amortized. However, both goodwill and trade names are subject to annual impairment testing. The Company amortizes its finite-lived intangible assets on a straight-line basis over the estimated period of benefit, generally seven to 17 years. See Note 3 for additional information.
	The impairment evaluation for goodwill is conducted annually using a two-step process. In the first step, the fair value of each reporting unit is compared to the carrying amount of the reporting unit, including goodwill. The estimated fair value of the reporting unit is determined using discounted cash flows and a market-based approach. If the estimated fair value of the reporting unit is less than the carrying amount of the reporting unit, then a second step must be completed in order to determine the amount of the goodwill impairment that should be recorded. In the second step, the implied fair value of the reporting unit’s goodwill is determined by allocating the reporting unit’s fair value to all of its assets and liabilities, other than goodwill, in a manner similar to a purchase price allocation. If the resulting implied fair value of the goodwill that results from the application of this second step is less than the carrying amount of the goodwill, an impairment charge is recorded for the difference. Currently, the Company defines the reporting units to be Del Frisco’s and Sullivan’s concepts. The Company performs its annual impairment test as of its year-end.
	The evaluation of the carrying amount of other intangible assets with indefinite lives is made annually by comparing the carrying amount of these assets to their estimated fair value. The estimated fair value is determined on the basis of existing market-based conditions as well as discounted future cash flow or the royalty-relief method for trade names. If the estimated fair value is less than the carrying amount, an impairment charge is recorded to reduce the asset to its estimated fair value.
	The valuation approaches used to determine fair value of each reporting unit and other intangible assets are subject to key judgments and assumptions about revenue growth rates, operating margins, weighted average cost of capital and comparable company and acquisition market multiples. When developing these key judgments and assumptions, which are sensitive to change, management considers economic, operational and market conditions that could impact the fair value. The judgments and assumptions used are consistent with what management believes hypothetical market participants would use. However, estimates are inherently uncertain and represent only reasonable expectations regarding future developments.
	Loan Costs
	Loan costs are stated at cost and amortized using the effective interest method over the life of the related loan.
	Deferred Compensation Plan
	In connection with the Company’s deferred-compensation plan, the Company has created a grantor trust to which it contributes amounts equal to employee participants’ qualified deferrals and the Company’s matching portion. The plan is informally funded using life insurance policies and mutual funds held by the grantor trust. All assets held by the grantor trust remain the property of the Company; however, the Company does not currently intend to use such assets for any purpose other than to fund payments to the participants pursuant to the terms of the deferred-compensation plan. The assets of the plan consist principally of cash surrender values of the life insurance policies. Because the investment assets of the deferred-compensation plan are assets of the Company and would be subject to general claims by creditors in the event of the Company’s insolvency, the accompanying consolidated balance sheets reflect such investments as assets, with a liability for deferred compensation reflected in long-term liabilities for amounts owed to employees. During fiscal 2013, the mutual fund investments were sold and the proceeds were used to purchase additional life insurance policies.
	Impairment of Long-Lived Assets
	Property and equipment and finite-life intangibles are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. The Company reviews applicable finite-lived intangible assets and long-lived assets related to each restaurant on a periodic basis. The Company’s assessment of recoverability of property and equipment and finite-lived intangible assets is performed at the component level, which is generally an individual restaurant. When events or changes in circumstances indicate an asset may not be recoverable, the Company estimates the future cash flows expected to result from the use of the asset. If the sum of the expected undiscounted future cash flows is less than the carrying value of the asset, an impairment loss is recognized. The impairment loss is recognized by measuring the difference between the carrying value of the assets and the estimated fair value of the assets. The Company’s estimates of fair values are based on the best information available and require the use of estimates, judgments, and projections. The actual results may vary significantly from the estimates.
	During fiscal 2011, the Company determined that the carrying amount of one of its Sullivan’s restaurants was most likely not recoverable. Therefore, the Company recorded a non-cash impairment charge of $1,400, which represents the difference between the carrying value of the restaurant assets and their estimated fair value, which was based on an estimated sales price. As this restaurant was closed and sold in fiscal 2012 (see Note 16), this amount is included in loss from discontinued operations in the consolidated statements of income and comprehensive income.
	During fiscal 2013, the Company determined that the carrying amount of one of its Sullivan’s restaurants was most likely not recoverable. Therefore, the Company recorded a non-cash impairment charge of $2,360, which represents the difference between the carrying value of the restaurant assets and their estimated fair value, which was based on an estimated sales price. This amount is included in non-cash impairment charges in the consolidated statements of income and comprehensive income.
	Self-Insurance Reserves
	The Company maintains self-insurance programs for its workers’ compensation and general liability insurance programs. In order to minimize the exposure under the self-insurance programs, the Company has purchased stop-loss coverage both on a per-occurrence and on an aggregate basis. The self-insured losses under the programs are accrued based on the Company’s estimate of the ultimate expected liability for both claims incurred and on an incurred but not reported basis. The establishment of such accruals for self-insurance involves certain management judgments and assumptions regarding the frequency or severity of claims, the historical patterns of claim development, and the Company’s experience with claim-reserve management and settlement practices. To the extent actual results differ from the assumptions used to develop the accruals, such unanticipated changes may produce significantly different amounts of expense than those estimated under the self-insurance programs.
	Income Taxes
	The Company uses the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based on differences between financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The Company regularly evaluates the likelihood of realization of tax benefits derived from positions it has taken in various federal and state filings after consideration of all relevant facts, circumstances, and available information. For those tax benefits deemed more likely than not that will be sustained, the Company recognizes the benefit it believes is cumulatively greater than 50% likely to be realized. To the extent the Company were to prevail in matters for which accruals have been established or be required to pay amounts in excess of recorded reserves, the effective tax rate in a given financial statement period could be materially impacted.
	Advertising Costs
	Advertising costs are expensed as incurred. Advertising expense for the fiscal years ended December 27, 2011, December 25, 2012, and December 31, 2013 was $4,246,  $4,682 and $5,663, respectively.
	Revenue Recognition
	Revenue from restaurant sales is recognized when food and beverage products are sold. Proceeds from the sale of gift cards are recorded as deferred revenue at the time of sale and recognized as income when the gift card is redeemed by the holder or the likelihood of redemption becomes remote (gift card breakage) and the Company determines there is no legal obligation to remit the value of the unredeemed gift cards to governmental agencies. The Company determines the gift card breakage rate based upon historical redemption patterns. Certain of the Company’s gift cards are sold on a discount and the net value (face value to be redeemed less the discount offered) is deferred until redeemed or breakage is deemed appropriate. The Company has deemed gift card breakage income immaterial for fiscal years 2011, 2012 and 2013, and it is included in revenues in the consolidated statements of income and comprehensive income. The Company excludes from revenue any taxes assessed by governmental agencies that are directly imposed on revenue-producing transactions between the Company and a customer.
	Stock-Based Compensation
	In connection with the IPO, the Company adopted the Del Frisco’s Restaurant Group, Inc. 2012 Long-Term Equity Incentive Plan (the “2012 Plan”), which allows the Company’s Board of Directors to grant stock options, restricted stock, restricted stock units, deferred stock units and other equity-based awards to directors, officers, key employees and other key individuals performing services for the Company. The Company recognizes stock-based compensation in accordance with “Compensation—Stock Compensation,” FASB ASC Topic 718 (Topic 718). Stock-based compensation cost includes compensation cost for all share-based payments granted based on the grant date fair value estimated in accordance with the provisions of Topic 718. Compensation cost is recognized on a straight-line basis, net of estimated forfeitures, over the requisite service period of each award.
	Reclassifications
	Certain amounts from the prior years have been reclassified to conform with the fiscal 2013 presentation.
	Recently Issued Accounting Standards
	In May 2011, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2011-04, Fair value Measurement (Topic 820), Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS . Many of the amendments in this update change the wording used in the existing guidance to better align generally accepted accounting principles in the United States with International Financial Reporting Standards and to clarify the FASB’s intent on various aspects of the fair value guidance. The update also requires increased disclosure of quantitative information about unobservable inputs used in a fair value measurement that is categorized within Level 3 of the fair value hierarchy. The update was effective for the Company beginning in fiscal 2012 and has been applied prospectively. Other than requiring additional disclosures, the new guidance did not have a significant impact on the Company’s consolidated financial statements upon adoption.
	In June 2011, the FASB issued ASU 2011-05, Comprehensive Income (Topic 220), Presentation of Comprehensive Income, which requires the Company to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The update eliminates the option to present the components of other comprehensive income as part of the statement of equity. In December 2011, the FASB issued ASU 2011-12, Comprehensive Income (Topic 220), Deferral of Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in ASU 2011-05, to defer the effective date of the specific requirement to present items that are reclassified out of accumulated other comprehensive income to net income alongside their respective components of net income and other comprehensive income. All other provisions of the update were effective for the Company in fiscal 2012 and have been applied retrospectively.
	In September 2011, the FASB issued ASU 2011-08, Intangible-Goodwill and Other (Topic 350), Testing Goodwill for Impairment, which permits an entity to make a qualitative assessment of whether it is more likely than not that a reporting unit’s fair value is less than its carrying value before applying the two-step goodwill impairment model that is currently in place. If it is determined through qualitative assessment that a reporting unit’s fair value is more likely than not greater than its carrying value, the remaining impairment steps would be unnecessary. The qualitative assessment is optional, allowing the Company to go directly to the quantitative assessment. All provisions of the update were effective for the Company in fiscal 2012. The Company does not believe the new guidance had a significant impact on its consolidated financial statements.
	In July 2012, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) 2012-02, Intangibles—Goodwill and Other (Topic 350), Testing Indefinite Lived Intangible Assets for Impairment. This ASU simplifies the guidance for impairment testing of indefinite-lived intangible assets other than goodwill and gives companies the option to assess qualitative factors to determine whether it is necessary to perform a quantitative impairment test. Companies electing to perform a qualitative assessment are no longer required to calculate the fair value of an indefinite-lived intangible asset unless the company determines, based on a qualitative assessment, that it is “more likely than not” that the asset is impaired. This update is effective for annual and interim impairment tests performed in fiscal years beginning after September 15, 2012. All provisions of the update are effective for the Company in fiscal 2013. The Company does not believe the new guidance had a significant impact on its consolidated financial statements.

		$	110,643	$	110,643
	Licensing contract rights and favorable lease rights are being amortized using the straight-line method over the estimated lives of the related contracts and agreements, which are seven to nine years for favorable leasehold interest and 17 years for licensing contract rights. Liquor licenses that are transferable are carried at cost. Such licenses are reviewed for impairment on an annual basis.
	Goodwill is allocated to the Del Frisco’s and Sullivan’s reporting units, respectively, as follows: $43,928 and $31,437 at December 25, 2012 and December 31, 2013. A portion of the goodwill allocated to the Sullivan’s location that was sold in fiscal 2012 was written off in fiscal 2012. See Note 16 for further discussion of discontinued operations.
	The Company has estimated that annual amortization expense will amount to approximately $159 for 2014, $132 for 2015, $96 for 2016, $88 for 2017, and $88 for 2018.
	Amortization expense was $166,  $169 and $169 for the years ended December 27, 2011, December 25, 2012, and December 31, 2013, respectively.
	The Company performed the annual test for impairment of goodwill and intangible assets and concluded that no impairment existed as of December 27, 2011, December 25, 2012 or December 31, 2013; accordingly, no impairment losses were recorded.
	On February 1, 2012, the Company entered into an agreement to terminate a license agreement with the licensee operating a Del Frisco’s in Orlando, Florida effective June 1, 2013. The original licensing agreement has been amortized over the expected term of the agreement, and has a remaining book value of $612 as of December 31, 2013. Under the agreement, in exchange for the Company surrendering its right to receive licensing fees from January 1, 2012 through June 1, 2013 and making a one-time $25 payment to the licensee, the Company will have the rights to open and operate any of its restaurants in the three counties that make up the Orlando metropolitan area no earlier than January 1, 2015. The Company accounted for this as an exchange of non-monetary assets, for which the Company has concluded that the fair value of the asset surrendered approximates its book value and therefore no gain or loss has been recorded on the exchange. To determine the fair value of the asset surrendered, the Company utilized a discounted cash flow method that applied a discount rate of 11.5%, the Company’s weighted-average cost of capital, to the future estimated cash flows to be received over the remaining term, including expected renewal, of the license agreement.

	(4) Related Party Transactions
	Management and Accounting Fees Paid to Related Party
	Management and accounting fees paid to related party include charges from LSM, which was an indirect wholly owned subsidiary of the Fund. These charges totaled $269 for the year ended December 27, 2011. The charges were primarily for accounting, risk management, human resources and benefits administration, legal, management information services, and other shared support services. The amounts that are included in management fees to related party in the accompanying consolidated statements of income and comprehensive income were charged pursuant to a shared service agreement formerly between the Company and LSM, which was terminated at the beginning of fiscal 2011. The Company cannot estimate with reasonable certainty what the charges for similar services would have been on a stand-alone basis. However, the Company believes that the charges are indicative of what it would have incurred on a stand-alone basis.
	At the date of Acquisition, the Company entered into an agreement with Hudson Advisors, L.L.C. (Hudson), an affiliate of certain entities that held an indirect investment interest in the Company. Pursuant to the agreement, Hudson provided certain asset management and advisory services to the Company. During the years ended December 27, 2011 and December 25, 2012, the Company incurred charges for such services of $3,129 and $1,252, respectively. This agreement was terminated upon consummation of the IPO, as discussed in Note 1.
	Transaction Bonuses
	In connection with the IPO, certain executives of the Company earned transaction bonuses of $1,462. These bonuses were earned under a letter agreement, as amended, with Wagon, in which certain executives of the Company are eligible to receive a transaction bonus upon the occurrence of an eligible transaction. Wagon is responsible to fund the transaction bonus. As this bonus is contingent upon employment with the Company, the Company is required to record the expense of these bonuses and recognize the funding by Wagon as additional paid in capital. $1,462 was recorded as an expense to the Company and $1,440 was recorded as a capital contribution by Wagon in fiscal 2012, which was used by the Company to pay these bonuses. Associated with the completion of the secondary public offerings in the first, third and fourth quarters of fiscal 2013, similar to the 2012 treatment, the Company recorded $8,355 in transaction bonuses expense and $8,234 in additional paid in capital as a capital contribution by Wagon.
	General and Administrative Expenses
	Upon completion of the IPO, the Company entered into a Transition Services Agreement with an affiliate of the Fund to provide certain limited support services, including legal and risk management, until the Company could complete transition of these functions to internal or third-party resources. General and administrative expenses include charges of approximately $73 and $30 for these services in fiscal 2012 and 2013, respectively. This agreement was terminated in the third quarter of 2013.

Leases	'
	(5) Leases
	The Company leases certain facilities under noncancelable operating leases with terms expiring between 2014 and 2034. The leases have renewal options ranging from five to 20 years, which are exercisable at the Company’s option. In addition, certain leases contain escalation clauses based on a fixed percentage increase and provisions for contingent rentals based on a percentage of gross revenues, as defined. Total rental expense amounted to $11,170,  $13,065 and $15,875 including contingent rentals of approximately $2,682,  $3,240 and $3,490 for the years ended December 27, 2011, December 25, 2012, and December 31, 2013, respectively.
	Future minimum lease payments under noncancelable operating leases include renewal option periods for certain leases when such option periods are included for purposes of calculating straight-line rents. At December 31, 2013, future minimum rentals for each of the next five years and in total are as follows:
	2014	$	14,847
	2015		16,153
	2016		16,303
	2017		15,968
	2018		16,004
	Thereafter		194,234
	Total minimum lease payments	$	273,509
	During 2011, the Company entered into a sale-leaseback arrangement with a private investor group. Under the arrangement, the Company sold the land and building of two of its Del Frisco’s restaurants located in Denver, Colorado and Ft. Worth, Texas and leased them back for a term of 15 years with options to renew. The sale-leaseback transactions do not provide for any continuing involvement by the Company other than a normal lease where the Company intends to use the property during the lease term. The leases were accounted for as operating leases. The aggregate annual lease obligation for the first year of the arrangement was approximately $1,151 with lease rental escalating every five years thereafter. The net proceeds from the transaction were approximately $13,235. Approximately $10,405 of the net proceeds were used to pay down the Company’s indebtedness under its credit facility. The Company realized a gain of approximately $8,699 which has been deferred as a component of deferred rent obligations and is being amortized over the life of the leases as a reduction in rent expense.

	In the second quarter of fiscal 2013, the Company determined that a deferred tax asset of $535 recorded in the fourth quarter of fiscal 2012 relating to local income tax net operating loss carryforwards was not realizable, as the related net operating losses originated in years from which the carryforward period had expired.  The Company corrected the deferred tax asset account resulting in a non-cash $535 cumulative adjustment to record additional income tax expense in the second quarter of fiscal 2013. The adjustment did not impact historical cash flows and will not impact the timing of future income tax payments. Prior years’ financial statements were not restated as the impact of these issues was immaterial to previously reported results for any individual prior year and fiscal 2012.
	Deferred income taxes reflect the net effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and amounts used for income tax purposes. Significant components of deferred tax assets and liabilities are presented below (in thousands):
		December 25,			December 31,
		2012			2013

	Total deferred tax liabilities		23,964			31,168
	Net deferred tax liabilities	$	-8,725		$	-12,402
	The Company accounts for unrecognized tax benefits in accordance with the provisions of FASB guidance which, among other directives, requires uncertain tax positions to be recognized only if they are more likely than not to be upheld based on their technical merits. The measurement of the uncertain tax position is based on the largest benefit amount that is more likely than not (determined on a cumulative probability basis) to be realized upon settlement.
	The Company may, from time to time, be assessed interest or penalties by major tax jurisdictions, although any such assessments historically have been minimal and immaterial to the Company’s financial results. In the event the Company receives an assessment for interest and penalties, it has been classified in the consolidated financial statements as income tax expense. Generally, the Company’s federal, state, and local tax returns for years subsequent to 2009 remain open to examination by the major taxing jurisdictions to which the Company is subject.
	At December 27, 2011 and December 25, 2012, the Company’s unrecognized tax benefits totaled approximately $1,631, related primarily to acquisitions and state tax issues. At December 31, 2013, the Company’s unrecognized tax benefits totaled approximately $1,386, related primarily to state tax issues. The Company does not believe its uncertain tax positions will change materially during the next 12 months. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in thousands):
			Year Ended

	The Company accrues interest and penalties in its tax provision. As of December 25, 2012 and December 31, 2013, accrued interest and penalties included in the consolidated balance sheets totaled $2,457 and $2,362, respectively. The change in interest and penalties associated with the Company’s unrecognized tax benefits is included as a component of the Other, net line of the effective tax rate reconciliation.

Long-Term Debt [Abstract]	'
Long-Term Debt	'
	(7) Long-Term Debt
	On October 15, 2012, the Company entered into a new credit facility that provides for a three-year unsecured revolving credit facility of up to $25,000.  Borrowings under the new credit facility bear interest at a rate of LIBOR plus 1.50%. The Company is required to pay a commitment fee equal to 0.25% per annum on the available but unused revolving loan facility. The credit facility is guaranteed by certain subsidiaries of the Company. The new credit facility contains various financial covenants, including a maximum ratio of total indebtedness to EBITDA, as defined in the credit agreement, and minimum fixed charge coverage, as defined in the credit agreement. The new credit facility also contains covenants restricting certain corporate actions, including asset dispositions, acquisitions, the payment of dividends, changes of control, the incurrence of indebtedness and providing financing or other transactions with affiliates. The Company was in compliance with all of the debt covenants as of December 31, 2013. As of December 31, 2013, the outstanding balance on the Company’s revolving credit facility was $0. Under the revolving loan commitment, the Company had approximately $25,000 of borrowings available under its revolving credit facility, less $761 in letter of credit commitments.
	On July 29, 2011, the Company terminated its amended 2007 credit facility and replaced it with the 2011 credit facility that provides for a five-year term loan of $70,000 and a five-year revolving credit facility of up to $10,000.  Borrowings under the 2011 credit facility bore interest at a rate between LIBOR plus 4.75% and LIBOR plus 5.75%, depending on the Company’s leverage ratio. Interest was payable quarterly. Principal payments were due in quarterly payments of $875 commencing September 30, 2013 with the balance due July 29, 2016. The Company was required to pay a commitment fee equal to 0.5% per annum on the available but unused revolving loan facility. The 2011 credit facility was secured by substantially all of the Company’s assets. The 2011 credit facility contained various financial covenants, including a maximum ratio of total indebtedness to EBITDA, as defined in the credit agreement, a minimum amount of EBITDA plus corporate general and administrative expenses, a minimum ratio of EBITDA plus certain non-recurring items to fixed charges (including consolidated capital expenses) and a minimum level of liquidity, as defined in the credit agreement. The 2011 credit facility also contained covenants restricting certain corporate actions, including asset dispositions, acquisitions, the payment of dividends, changes of control, the incurrence of indebtedness and providing financing or other transactions with affiliates. During 2012 the Company repaid all remaining balances outstanding on the 2011 credit facility with proceeds from the IPO.

	The Company provides two retirement benefit plans to participants. The salary-reduction plans are provided through a qualified 401(k) plan and a nonqualified deferred compensation plan (the Plans). Under the Plans, employees who meet minimum service requirements and elect to participate may make contributions of up to 15% of their annual salaries under the 401(k) plan and up to 80% under the deferred-compensation plan. The Company may make additional contributions at the discretion of the Board of Directors. Expenses related to the Plans for the years ended, December 27, 2011, December 25, 2012 and December 31, 2013, totaled $1,006,  $1,256, and $1,724, respectively.

	Prior to the Acquisition, the Company guaranteed certain lease payments of Star’s subsidiaries in connection with the leasing of real estate for restaurant locations. As of December 31, 2013, the Company was responsible as guarantor for five of the leases of its former affiliates. The leases expire at various times through 2016. These guarantees will require payment by the Company only in an event of default by the former affiliate where it is unable to make the required lease payments. During 2011, the Company incurred expenses of $130 in connection with certain of these guarantees in return for releases from such guarantees which are included in other expenses. Management believes that any future payments required under these guarantees will not be significant. At December 31, 2013 the maximum potential amount of future payments the Company could be required to make as a result of the guarantees was $1,445.
	At December 31, 2013, the Company had outstanding letters of credit of $976, of which $215 were collateralized by restricted cash and $761 were outstanding on the Company’s revolving credit facility. The letters of credit typically act as guarantee of payment to certain third parties in accordance with specified terms and conditions.

Fair Value Measurement	'
	(12) Fair Value Measurement
	Under generally accepted accounting principles in the United States, the Company is required to measure certain assets and liabilities at fair value, or to disclose the fair value of certain assets and liabilities recorded at cost. Pursuant to these fair value measurement and disclosure requirements, fair value is defined as the price that would be received upon sale of an asset or paid upon transfer of a liability in an orderly transaction between market participants at the measurement date and in the principal or most advantageous market for that asset or liability. The fair value is calculated based on assumptions that market participants would use in pricing the asset or liability, not on assumptions specific to the entity. In addition, the fair value of liabilities includes consideration of non-performance risk, including the Company’s own credit risk. Each fair value measurement is reported in one of the following three levels:
		•	Level 1—valuation inputs are based upon unadjusted quoted prices for identical instruments traded in active markets.
		•	Level 2—valuation inputs are based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
		•	Level 3—valuation inputs are unobservable and typically reflect management’s estimates of assumptions that market participants would use in pricing the asset or liability. The fair values are therefore determined using model-based techniques that include option pricing models, discounted cash flow models, and similar techniques.
	The following tables present our financial assets and liabilities measured at fair value on a recurring basis at December 25, 2012 and December 31, 2013 (in thousands):
			Fair Value Measurements

	Deferred compensation plan investments (mutual funds)		1	$	2,216	$	—
	Deferred compensation plan liabilities		2	$	-8,415	$	-11,022
	There were no transfers among levels within the fair value hierarchy during the years ended December 25, 2012 or December 31, 2013. The carrying value of the Company’s cash and cash equivalents and restricted cash approximate fair value because of their short term nature, and are classified within Level 1 of the fair value hierarchy. The carrying value of the Company’s accounts payable approximate fair value because of their short term nature, and are classified within Level 2 of the fair value hierarchy.
	The Company has no derivative instruments at December 25, 2012 or December 31, 2013.

	The Company operates the Del Frisco’s, Sullivan’s, and Del Frisco’s Grille brands as operating segments. The concepts operate solely in the U.S. within the full-service dining industry, providing similar products to similar customers. Sales from external customers are derived principally from food and beverage sales, and the Company does not rely on any major customers as a source of sales. The concepts also possess similar economic characteristics, resulting in similar long-term expected financial performance characteristics. However, as Del Frisco’s restaurants typically have higher revenues, driven by their larger physical presence and higher check average, the Del Frisco’s, Sullivan’s, and Del Frisco’s Grille operating segments have varying operating income and restaurant-level EBITDA margins due to the leveraging of higher revenues on certain fixed operating costs such as management labor, rent, utilities, and building maintenance.
	The following table presents information about reportable segments for fiscal years 2011, 2012, and 2013 (in thousands):

	In addition to using consolidated results in evaluating the Company’s performance and allocating its resources, the Company’s chief operating decision maker uses restaurant-level EBITDA, which is not a measure defined by generally accepted accounting principles. Restaurant-level EBITDA is defined as operating income before pre-opening costs, general and administrative expenses, management and accounting fees paid to related party, asset advisory agreement termination fees, non-cash impairment charges, public offering transaction bonuses, secondary public offering costs and depreciation and amortization. Pre-opening costs are excluded because they vary in timing and magnitude and are not related to the health of ongoing operations. General and administrative expenses and management and accounting fees paid to related party are only included in the Company’s consolidated financial results as they are generally not specifically identifiable to individual operating segments as these costs relate to supporting all of the restaurant operations of the Company and the extension of the Company’s concepts into new markets. Depreciation and amortization is excluded because it is not an ongoing controllable cash expense and it is not related to the health of ongoing operations. Property and equipment is the only balance sheet measure used by the Company’s chief operating decision maker in allocating resources. See table below for a reconciliation of restaurant-level EBITDA to operating income.

	Basic earnings per share (“EPS”) data is computed based on the weighted average number of shares of common stock outstanding during the period. Diluted EPS data is computed based on the weighted average number of shares of common stock outstanding, including all potentially issuable shares of common stock. During fiscal 2011, there were no outstanding stock options or other dilutive securities and therefore they were not included in the dilutive calculation. Diluted earnings per share for fiscal 2012 excludes stock options of 825,000, which were outstanding during the period but were anti-dilutive. Diluted earnings per share for fiscal 2013 excludes options to purchase 423,579 shares of common stock, which were outstanding during the period, but were anti-dilutive.

	2012 Long-Term Equity Incentive Plan
	In connection with the IPO, the Company adopted the Del Frisco’s Restaurant Group, Inc. 2012 Long-Term Equity Incentive Plan (the “2012 Plan”), which allows the Company’s Board of Directors to grant stock options, restricted stock, restricted stock units, deferred stock units and other equity-based awards to directors, officers, key employees and other key individuals performing services for the Company. The 2012 Plan provides for granting of options to purchase shares of common stock at an exercise price not less than the fair value of the stock on the date of grant. Options are exercisable at various periods ranging from one to four years from date of grant. The 2012 Plan has 2,232,800 shares authorized for issuance under the plan. There are 1,496,525 shares of common stock issuable upon exercise of currently outstanding options at December 31, 2013, and 707,800 shares available for future grants.
	The following table details the Company’s total stock option compensation costs during the years ended December 25, 2012 and December 31, 2013 as well as where the costs were expensed (in thousands):
		Fiscal Year Ended
		December 25,			December 31,

	Restaurant operating expenses	$	74		$	332
	General and administrative costs		304			1,357
	Total stock compensation cost	$	378		$	1,689

		31-Dec-13
		Shares		Weighted average exercise price			Weighted average Remaining Contractual Term	Aggregate Intrinsic Value ($000's)
	Outstanding at beginning of year	825,000		$	13.09

	Options exercisable at end of period	166,400		$	13.12		8.61 years	$	1,740
	The intrinsic value of options exercised during fiscal 2013 was $215.  A summary of the status of non-vested shares as of December 31, 2013 and changes during fiscal 2013 is presented below:
		31-Dec-13
		Shares			Weighted average Grant-Date Fair Value
	Non-vested shares at beginning of year	825,000		$	4.93
	Granted	765,500			8.30
	Vested	-194,875			4.94
	Forfeited	-65,500			5.48
	Non-vested shares at end of period	1,330,125		$	6.84
	As of December 31, 2013, there was $7,864 of total unrecognized compensation cost related to non-vested stock options. This cost is expected to be recognized over a period of approximately 3.09 years. The total fair value of shares vested during fiscal 2013 was $963.
	The following table details the values from and assumptions for the Black-Scholes option pricing model for stock options issued during the fiscal years ended December 25, 2012 and December 31, 2013.
		2012		2013
	Weighted average grant date fair value	$4.82		$8.30
	Weighted average risk-free interest rate	0.58%		1.44%
	Weighted average expected life	5.4 years		5.49 years
	Weighted average volatility	40.21%		41.65%
	Expected dividend	—		—
	The Black-Scholes option valuation model requires the input of highly subjective assumptions, including the expected life of the stock-based award. The assumptions above represent management’s best estimates, but these estimates involve inherent uncertainties and the application of management’s judgment. The expected term of options granted is based on a representative peer group with similar employee groups and expected behavior. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury constant maturities rate in effect at the time of grant. The Company utilized a weighted rate for expected volatility based on a representative peer group with a similar expected term of options granted. Outstanding options granted under the Company’s 2012 Equity Incentive Plan are subject to a four year vesting period and have a ten year maximum contractual term.
	In addition, the Company is required to estimate the expected forfeiture rate and only recognizes expense for those shares expected to vest. If the actual forfeiture rate is materially different from the Company’s estimate, the share-based compensation expense could be materially different.
	2007 Long-Term Equity Incentive Compensation
	In April 2007, Holdings provided long-term incentives to certain of the Company’s officers through the issuance of equity incentive awards in the form of its Class C interests. In addition, these same officers acquired Class B interests in Holdings for $525, which amount was subsequently contributed to the Company by Holdings. The Class B interests of Holdings, which were purchased at their estimated fair value, were fully vested upon issuance and have a stated return but did not participate in any increase in the value of Holdings. The Class C interests of Holdings, which represented a 7% equity participation in Holdings, vested ratably over a five-year period based on both continuing employment and the achievement of performance targets from 2007 through 2011. The Class C interests vested 7.5% annually over five years if the holder was employed on December 31 of each year . The annual compensation expense related to this 7.5% was based upon the value of Class C interests calculated at April 30, 2007, the date of grant. The remaining Class C interests vested 12.5% annually in each of the five years if performance targets of each such year are achieved by December 31 of such year; however, these interests, subject to vesting upon achievement of performance targets, were forfeited and not eligible to vest at a later date if the performance targets for such year are not achieved. These awards were accounted for as variable awards, which are revalued at the end of each reporting period until such interests are either vested or forfeited. Those Class C interests that have not been previously forfeited become fully vested if there is a change of control in the ownership of the Company or Holdings, as set forth in the operating agreement of Holdings. During 2010 and 2011, both the 7.5% service-based and the 12.5% performance-based of Class C interests vested for those participants still employed by the Company at the end of each year.
	A contemporaneous independent appraisal was conducted by an unrelated valuation specialist to value the Class B and Class C interests at the date of grant as well as for the Class C interests at December 30, 2008. This valuation used the option value method, as further discussed below, to determine the estimated fair value of the interests. The estimated fair value of the Class B interests approximated the purchase value by the officers and was vested upon issuance, and therefore, no compensation cost was recorded on the Class B interests.
	The estimated fair value of the Class C interests was calculated based on the estimated market value of the Company with discounts applied that related to lack of marketability, restrictions on the transferability of the Class C interests, and the preferences of Class A and B interests. The Class C interests only had value after the Class A and B interests are paid the amount invested in Holdings plus the stated rate of return of 12% on such invested amounts. The estimated fair value of the Class C interests was calculated using the option value method based on a risk-free interest rate of 0.62%; an expected life of approximately 1.75 years; and expected volatility of 34%, at December 28, 2010 and December 27, 2011; and an estimated dividend yield of zero. The unrelated valuation specialist utilized the constant maturity treasury rate relative to the expected life for the expected risk-free interest rate, the volatility of comparable publicly traded companies for expected volatility, and the expected time between valuation date and a liquidity event for the expected life. This equity-based compensation totaled $170 and $101 for the years ended December 28, 2010 and December 27, 2011, respectively. The Company has recorded this equity-based compensation as a charge to earnings in its consolidated statements of income and comprehensive income with an affect to stockholders’ equity in its consolidated statements of changes in stockholders’ equity for the years ended December 28, 2010 and December 27, 2011, respectively. As of December 31, 2011, only one of the original three Class C interest holders was still employed by the Company and all interest in Class B and Class C awards were fully vested.
	During 2011, the Company distributed $357 to Wagon Holdings, which was recorded as a cash distribution to parent and is reflected on the Statement of Changes in Member’s Equity. Wagon Holdings, in turn, paid a former executive of the Company $357 as consideration for his surrendering his Class B and Class C interests. The consideration paid for surrender solely related to the value of Class B interests which was the amount invested in Holdings plus the stated rate of return of 12% on such invested amounts.

	On June 30, 2012, the Company closed its Dallas Sullivan’s location and on July 2, 2012, the Company completed the sale of the real property to a third party. The real property sold for $1,682, net of selling related expenses, which approximated its carrying value. In connection with the closure and sale of this restaurant, the Company allocated $739 in goodwill from the Sullivan’s reporting unit to this restaurant to determine the loss on the disposition. After this allocation, the total loss on the sale of this property was $465, net of tax. The Company previously recognized a non-cash asset impairment charge of $1,400 associated with this restaurant during fiscal 2011.
	The Company determined that this closure met the criteria for classification as discontinued operations. As a result, all historical operating results of this property are reflected within discontinued operations in the consolidated statements of comprehensive income (loss) for all periods presented. Loss from discontinued operations, net of tax is comprised of the following:

The Company believes that quarter-to-quarter comparisons of its financial results are not necessarily indicative of future performance.

Summary Of Significant Accounting Policies [Abstract]	'
Principles Of Consolidation	'
	Principles of Consolidation
	The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated.
Fiscal Year	'
	Fiscal Year
	The Company operates on a 52- or 53-week fiscal year ending the last Tuesday in December. Fiscal 2011 and 2012 included 52 weeks of operations, while fiscal 2013 included 53 weeks of operations.
Concentrations	'
	Concentrations
	The Company has certain financial instruments exposed to a concentration of credit risk, which consist primarily of cash and cash equivalents. The Company places cash with high-credit-quality financial institutions, and, at times, such cash may be in excess of the federal depository insurance limit.
	Additionally, the Company purchased a significant amount of total beef purchases from one supplier during fiscal 2011, 2012, and 2013, respectively. Due to the nature of the beef purchases, there are alternative sources of supply available; however, a change in suppliers could potentially cause increased costs.
Use Of Estimates	'
	Use of Estimates
	The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.
Cash And Cash Equivalents	'
	Cash and Cash Equivalents
	Cash and cash equivalents include currency on hand, demand deposits with banks or other financial institutions, credit card receivables, and short-term investments with maturities of three months or less when purchased. Cash and cash equivalents are carried at cost, which approximates fair value.
Financial Instruments	'
	Financial Instruments
	The Company considers the carrying amounts of cash and cash equivalents, short-term investments, receivables and accounts payable to approximate fair value based on the short-term nature of these items. Borrowings available under the credit facility at December 31, 2013 have variable interest rates that reflect currently available terms and conditions for similar debt.
Inventories	'
	Inventories
	Inventories, which primarily consist of food and beverages, are valued at the lower of cost, using the first-in, first-out (FIFO) method, or market.
Property And Equipment	'
	Property and Equipment
	Property and equipment are stated at cost. Maintenance, repairs, and renewals that do not enhance the value of or increase the lives of the assets are expensed as incurred. Buildings are depreciated using the straight-line method over their estimated useful lives of 20 to 25 years. Leasehold improvements are amortized using the straight-line method over the lesser of the estimated useful lives of the assets of 20 years or the expected term of the lease, including cancelable optional renewal periods when failure to exercise such renewal options would result in an economic penalty to the Company. Furniture, fixtures, and equipment are depreciated using the straight-line method over three to seven years, which are the estimated useful lives of the assets.
	Interest is capitalized in connection with the construction of restaurant facilities. The capitalized interest is recorded as part of the asset to which it relates and is amortized over the asset’s estimated useful life. Capitalized interest was $204,  $104 and $0 for the years ended December 27, 2011, December 25, 2012 and December 31, 2013, respectively.
Operating Leases	'
	Operating Leases
	The Company leases restaurants under operating leases. The majority of the Company’s leases provide for rent escalation clauses, contingent rental expense, and/or tenant improvement allowances.
	Rent expense is recognized on a straight-line basis over the expected term of the lease, which includes cancelable optional renewal periods that are reasonably assured to be exercised and where failure to exercise such renewal options would result in an economic penalty to the Company.
	Certain of the Company’s operating leases contain clauses that provide additional contingent rent based on a percentage of sales greater than certain specified target amounts. The Company recognizes contingent rent expense prior to the achievement of the specified target that triggers the contingent rent, provided achievement of that target is considered probable.
	The Company records tenant improvement allowances and other landlord incentives as a component of deferred rent which is amortized on a straight-line basis over the expected term of the lease.
Preopening Costs	'
	Preopening Costs
	Preopening costs, including labor costs, costs of hiring and training personnel, and certain other costs related to opening new restaurants, are expensed when the costs are incurred.
Goodwill And Other Intangible Assets	'
	Goodwill and Other Intangible Assets
	The Company’s intangible assets primarily include goodwill, trade names, and licensing agreements, arising from the 2006 Acquisition. The Company’s trade names include “Del Frisco’s Double Eagle Steak House” and “Sullivan’s Steakhouse,” both of which have indefinite lives and, accordingly, are not subject to amortization. The trade names are used in the advertising and marketing of the restaurants and are widely recognized and accepted by consumers in their respective markets for providing its customers an enjoyable fine-dining experience. Goodwill represents the excess of costs over the fair value of the net assets acquired.
	Goodwill and intangible assets that have indefinite useful lives are not amortized. However, both goodwill and trade names are subject to annual impairment testing. The Company amortizes its finite-lived intangible assets on a straight-line basis over the estimated period of benefit, generally seven to 17 years. See Note 3 for additional information.
	The impairment evaluation for goodwill is conducted annually using a two-step process. In the first step, the fair value of each reporting unit is compared to the carrying amount of the reporting unit, including goodwill. The estimated fair value of the reporting unit is determined using discounted cash flows and a market-based approach. If the estimated fair value of the reporting unit is less than the carrying amount of the reporting unit, then a second step must be completed in order to determine the amount of the goodwill impairment that should be recorded. In the second step, the implied fair value of the reporting unit’s goodwill is determined by allocating the reporting unit’s fair value to all of its assets and liabilities, other than goodwill, in a manner similar to a purchase price allocation. If the resulting implied fair value of the goodwill that results from the application of this second step is less than the carrying amount of the goodwill, an impairment charge is recorded for the difference. Currently, the Company defines the reporting units to be Del Frisco’s and Sullivan’s concepts. The Company performs its annual impairment test as of its year-end.
	The evaluation of the carrying amount of other intangible assets with indefinite lives is made annually by comparing the carrying amount of these assets to their estimated fair value. The estimated fair value is determined on the basis of existing market-based conditions as well as discounted future cash flow or the royalty-relief method for trade names. If the estimated fair value is less than the carrying amount, an impairment charge is recorded to reduce the asset to its estimated fair value.
	The valuation approaches used to determine fair value of each reporting unit and other intangible assets are subject to key judgments and assumptions about revenue growth rates, operating margins, weighted average cost of capital and comparable company and acquisition market multiples. When developing these key judgments and assumptions, which are sensitive to change, management considers economic, operational and market conditions that could impact the fair value. The judgments and assumptions used are consistent with what management believes hypothetical market participants would use. However, estimates are inherently uncertain and represent only reasonable expectations regarding future developments.
Loan Costs	'
	Loan Costs
	Loan costs are stated at cost and amortized using the effective interest method over the life of the related loan.
Deferred Compensation Plan	'
	Deferred Compensation Plan
	In connection with the Company’s deferred-compensation plan, the Company has created a grantor trust to which it contributes amounts equal to employee participants’ qualified deferrals and the Company’s matching portion. The plan is informally funded using life insurance policies and mutual funds held by the grantor trust. All assets held by the grantor trust remain the property of the Company; however, the Company does not currently intend to use such assets for any purpose other than to fund payments to the participants pursuant to the terms of the deferred-compensation plan. The assets of the plan consist principally of cash surrender values of the life insurance policies. Because the investment assets of the deferred-compensation plan are assets of the Company and would be subject to general claims by creditors in the event of the Company’s insolvency, the accompanying consolidated balance sheets reflect such investments as assets, with a liability for deferred compensation reflected in long-term liabilities for amounts owed to employees. During fiscal 2013, the mutual fund investments were sold and the proceeds were used to purchase additional life insurance policies.
Impairment Of Long-Lived Assets	'
	Impairment of Long-Lived Assets
	Property and equipment and finite-life intangibles are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. The Company reviews applicable finite-lived intangible assets and long-lived assets related to each restaurant on a periodic basis. The Company’s assessment of recoverability of property and equipment and finite-lived intangible assets is performed at the component level, which is generally an individual restaurant. When events or changes in circumstances indicate an asset may not be recoverable, the Company estimates the future cash flows expected to result from the use of the asset. If the sum of the expected undiscounted future cash flows is less than the carrying value of the asset, an impairment loss is recognized. The impairment loss is recognized by measuring the difference between the carrying value of the assets and the estimated fair value of the assets. The Company’s estimates of fair values are based on the best information available and require the use of estimates, judgments, and projections. The actual results may vary significantly from the estimates.
	During fiscal 2011, the Company determined that the carrying amount of one of its Sullivan’s restaurants was most likely not recoverable. Therefore, the Company recorded a non-cash impairment charge of $1,400, which represents the difference between the carrying value of the restaurant assets and their estimated fair value, which was based on an estimated sales price. As this restaurant was closed and sold in fiscal 2012 (see Note 16), this amount is included in loss from discontinued operations in the consolidated statements of income and comprehensive income.
	During fiscal 2013, the Company determined that the carrying amount of one of its Sullivan’s restaurants was most likely not recoverable. Therefore, the Company recorded a non-cash impairment charge of $2,360, which represents the difference between the carrying value of the restaurant assets and their estimated fair value, which was based on an estimated sales price. This amount is included in non-cash impairment charges in the consolidated statements of income and comprehensive income.
Self-Insurance Reserves	'
	Self-Insurance Reserves
	The Company maintains self-insurance programs for its workers’ compensation and general liability insurance programs. In order to minimize the exposure under the self-insurance programs, the Company has purchased stop-loss coverage both on a per-occurrence and on an aggregate basis. The self-insured losses under the programs are accrued based on the Company’s estimate of the ultimate expected liability for both claims incurred and on an incurred but not reported basis. The establishment of such accruals for self-insurance involves certain management judgments and assumptions regarding the frequency or severity of claims, the historical patterns of claim development, and the Company’s experience with claim-reserve management and settlement practices. To the extent actual results differ from the assumptions used to develop the accruals, such unanticipated changes may produce significantly different amounts of expense than those estimated under the self-insurance programs.
Income Taxes	'
	Income Taxes
	The Company uses the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based on differences between financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The Company regularly evaluates the likelihood of realization of tax benefits derived from positions it has taken in various federal and state filings after consideration of all relevant facts, circumstances, and available information. For those tax benefits deemed more likely than not that will be sustained, the Company recognizes the benefit it believes is cumulatively greater than 50% likely to be realized. To the extent the Company were to prevail in matters for which accruals have been established or be required to pay amounts in excess of recorded reserves, the effective tax rate in a given financial statement period could be materially impacted.
Advertising Costs	'
	Advertising Costs
	Advertising costs are expensed as incurred. Advertising expense for the fiscal years ended December 27, 2011, December 25, 2012, and December 31, 2013 was $4,246,  $4,682 and $5,663, respectively.
Revenue Recognition	'
	Revenue Recognition
	Revenue from restaurant sales is recognized when food and beverage products are sold. Proceeds from the sale of gift cards are recorded as deferred revenue at the time of sale and recognized as income when the gift card is redeemed by the holder or the likelihood of redemption becomes remote (gift card breakage) and the Company determines there is no legal obligation to remit the value of the unredeemed gift cards to governmental agencies. The Company determines the gift card breakage rate based upon historical redemption patterns. Certain of the Company’s gift cards are sold on a discount and the net value (face value to be redeemed less the discount offered) is deferred until redeemed or breakage is deemed appropriate. The Company has deemed gift card breakage income immaterial for fiscal years 2011, 2012 and 2013, and it is included in revenues in the consolidated statements of income and comprehensive income. The Company excludes from revenue any taxes assessed by governmental agencies that are directly imposed on revenue-producing transactions between the Company and a customer.
Stock-Based Compensation	'
	Stock-Based Compensation
	In connection with the IPO, the Company adopted the Del Frisco’s Restaurant Group, Inc. 2012 Long-Term Equity Incentive Plan (the “2012 Plan”), which allows the Company’s Board of Directors to grant stock options, restricted stock, restricted stock units, deferred stock units and other equity-based awards to directors, officers, key employees and other key individuals performing services for the Company. The Company recognizes stock-based compensation in accordance with “Compensation—Stock Compensation,” FASB ASC Topic 718 (Topic 718). Stock-based compensation cost includes compensation cost for all share-based payments granted based on the grant date fair value estimated in accordance with the provisions of Topic 718. Compensation cost is recognized on a straight-line basis, net of estimated forfeitures, over the requisite service period of each award.
Reclassifications	'
	Reclassifications
	Certain amounts from the prior years have been reclassified to conform with the fiscal 2013 presentation.
Recently Issued Accounting Standards	'
	Recently Issued Accounting Standards
	In May 2011, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2011-04, Fair value Measurement (Topic 820), Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS . Many of the amendments in this update change the wording used in the existing guidance to better align generally accepted accounting principles in the United States with International Financial Reporting Standards and to clarify the FASB’s intent on various aspects of the fair value guidance. The update also requires increased disclosure of quantitative information about unobservable inputs used in a fair value measurement that is categorized within Level 3 of the fair value hierarchy. The update was effective for the Company beginning in fiscal 2012 and has been applied prospectively. Other than requiring additional disclosures, the new guidance did not have a significant impact on the Company’s consolidated financial statements upon adoption.
	In June 2011, the FASB issued ASU 2011-05, Comprehensive Income (Topic 220), Presentation of Comprehensive Income, which requires the Company to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The update eliminates the option to present the components of other comprehensive income as part of the statement of equity. In December 2011, the FASB issued ASU 2011-12, Comprehensive Income (Topic 220), Deferral of Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in ASU 2011-05, to defer the effective date of the specific requirement to present items that are reclassified out of accumulated other comprehensive income to net income alongside their respective components of net income and other comprehensive income. All other provisions of the update were effective for the Company in fiscal 2012 and have been applied retrospectively.
	In September 2011, the FASB issued ASU 2011-08, Intangible-Goodwill and Other (Topic 350), Testing Goodwill for Impairment, which permits an entity to make a qualitative assessment of whether it is more likely than not that a reporting unit’s fair value is less than its carrying value before applying the two-step goodwill impairment model that is currently in place. If it is determined through qualitative assessment that a reporting unit’s fair value is more likely than not greater than its carrying value, the remaining impairment steps would be unnecessary. The qualitative assessment is optional, allowing the Company to go directly to the quantitative assessment. All provisions of the update were effective for the Company in fiscal 2012. The Company does not believe the new guidance had a significant impact on its consolidated financial statements.
	In July 2012, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) 2012-02, Intangibles—Goodwill and Other (Topic 350), Testing Indefinite Lived Intangible Assets for Impairment. This ASU simplifies the guidance for impairment testing of indefinite-lived intangible assets other than goodwill and gives companies the option to assess qualitative factors to determine whether it is necessary to perform a quantitative impairment test. Companies electing to perform a qualitative assessment are no longer required to calculate the fair value of an indefinite-lived intangible asset unless the company determines, based on a qualitative assessment, that it is “more likely than not” that the asset is impaired. This update is effective for annual and interim impairment tests performed in fiscal years beginning after September 15, 2012. All provisions of the update are effective for the Company in fiscal 2013. The Company does not believe the new guidance had a significant impact on its consolidated financial statements.
