Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business and Basis of Presentation	Business and Basis of Presentation As of June 25, 2019 , Del Frisco’s Restaurant Group, Inc. ("we," "us," "our," “Del Frisco’s” or the “Company”) owned and operated 78 restaurants under the concept names of Del Frisco’s Double Eagle Steakhouse (“Double Eagle”), Barcelona Wine Bar (“Barcelona”), bartaco, and Del Frisco’s Grille (“Grille”). Of the 78 restaurants we operated at the end of the period covered by this report, there were 16 Double Eagle restaurants, 17 Barcelona restaurants, 21 bartaco restaurants, and 24 Grille restaurants in operation in 17 states and the District of Columbia. Recent Developments On June 27, 2018 (“Acquisition Date”), we completed the acquisition of all outstanding interests in Barteca Holdings, LLC ("Barteca Acquisition"), a Delaware limited liability company, and its subsidiaries (“Barteca”) for total cash consideration of $331.2 million , which represents a purchase price of $325 million plus customary adjustments including payments for cash remaining in the business. In connection with the completion of the Barteca Acquisition, we entered into a new credit agreement that provides for (i) senior secured term loans in an aggregate principal amount of $390.0 million (“Term Loan B”) and (ii) senior secured revolving credit commitments in an aggregate principal amount of $50.0 million (“Revolving Loan,” and, collectively with the term loans, the “2018 Credit Facility”). See Note 7 , Long-Term Debt in the notes to our condensed consolidated financial statements for information regarding our credit facility. On August 1, 2018, we entered into an underwriting agreement with certain underwriters with respect to (i) the sale by the Company of 11,250,000 shares of the Company’s common stock, par value $0.001 per share, to the underwriters and (ii) the grant by the Company to the underwriters of an option (the “Option”) to purchase up to 1,687,500 additional shares of the Company’s common stock (together, the “Shares”). The sale of the Shares, including the exercise in full of the Option, closed on August 6, 2018. The total proceeds of $97.8 million from the public offering of common stock were used to repay a portion of Term Loan B. See Note 7 , Long-Term Debt in the notes to our condensed consolidated financial statements. On August 27, 2018 we amended (the “First Amendment”) Term Loan B (“Amended Term Loan B”). The First Amendment amends the 2018 Credit Facility, to, among other things, provide the Company with additional term loans (“Additional Term Loans”) in an aggregate principal amount of $18.0 million . The First Amendment also amended the 2018 Credit Facility to increase the interest rate applicable to the Additional Term Loans and the existing term loans outstanding under the 2018 Credit Facility to, at our option, a rate per annum equal to either a LIBOR or a base rate, plus an applicable margin, which is equal to 6.00% for LIBOR rate loans and 5.00% for base rate loans. See Note 7 , Long-Term Debt in the notes to our condensed consolidated financial statements for information regarding our amended credit facility. On September 21, 2018, we sold all of the outstanding equity interests in our Sullivan’s Steakhouse business (“Sullivan’s") to Sullivan’s Holding LLC, a Delaware limited liability company and affiliate of Romano’s Macaroni Grill, for the total gross proceeds of approximately $32 million , subject to customary adjustments for inventory and cash. See Note 3 , Dispositions in the notes to our condensed consolidated financial statements for information regarding discontinued operations. On February 26, 2019, we entered into a joinder agreement with JPMorgan Chase Bank, N.A., as the incremental term lender and JPMorgan Chase Bank, N.A. as the administrative agent (the “Joinder Agreement”). The Joinder Agreement modifies the 2018 Credit Facility and provides the Company with incremental term loan commitments in a principal amount equal to $25.0 million . The Company drew the full amount of the incremental term loans on the date of the Joinder Agreement and received net proceeds of approximately $23.1 million . The Company used the net proceeds of the incremental term loans to repay a portion of the outstanding amounts under the 2018 Credit Facility. Since the repayment does not reduce the commitments under the 2018 Credit Facility, the transaction expanded the Company’s sources of liquidity without increasing leverage at this time. See Note 7 , Long-Term Debt in the notes to our condensed consolidated financial statements. On June 17, 2019, we entered into an amendment (the “Second Amendment”) to the 2018 Credit Facility to increase the percentage of Projected EBITDAR Margin that may be included when determining Consolidated EBITDAR for purposes of calculating the Financial Covenant (as defined in the 2018 Credit Facility). See Note 7 , Long-Term Debt in the notes to our condensed consolidated financial statements. On June 23, 2019, we entered into a definitive agreement to be acquired by affiliates of L Catterton, a consumer-focused private equity firm with over $15 billion of equity capital across six fund strategies in 17 offices globally. Under the terms of the agreement, affiliates of L Catterton will acquire all outstanding shares of the Company’s common stock for a total value of approximately $650 million . Company stockholders will receive $8.00 in cash per share. The Agreement and Plan of Merger, dated as of June 23, 2019, by and among the Company, Harlan Parent, Inc. and Harlan Merger Sub, Inc. was filed as an exhibit to our Current Report on Form 8-K filed with the SEC on June 24, 2019. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information. Accordingly, they do not include all the information and disclosures required by GAAP for complete financial statements. Operating results for the 13 weeks and 26 weeks ended June 25, 2019 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2019 . In the opinion of management, the unaudited condensed consolidated financial statements include all adjustments, consisting of normal recurring adjustments, considered necessary for a fair presentation. These unaudited condensed consolidated financial statements and related notes should be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for the fiscal year ended December 25, 2018 filed with the SEC on March 11, 2019 (the “2018 10-K”). The results of Sullivan's operations have been presented as discontinued operations for the 13 weeks and and 26 weeks ended June 26, 2018 . See Note 3 , Dispositions in the notes to our condensed consolidated financial statements for information regarding discontinued operations. We operate on a 52- or 53-week fiscal year ending the last Tuesday in December. Beginning in fiscal 2018, we changed to a fiscal quarter calendar where each quarter contains 13 weeks, other than in a 53-week year where the last quarter of the year will contain 14 weeks. Fiscal 2019 will be a 53-week fiscal year, fiscal 2018 was a 52-week fiscal year. We believe that a reporting basis comprised of four equal 13-week quarters is a more typical reporting format comparable to most companies in the restaurant industry and is easier to understand for our investors. Accounting Estimates The preparation of the unaudited condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. We base our estimates on historical experience and on various assumptions that are believed to be reasonable under the circumstances at the time. Actual amounts may differ from those estimates. Recently Adopted Accounting Pronouncements In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) ("ASU 2016-02"). which requires a lessee to recognize assets and liabilities for leases with lease terms of more than 12 months. The recognition, measurement and presentation of expenses and cash flows arising from a lease by a lessee will primarily depend on its classification as a finance (formerly capital) or operating lease. However, unlike previous GAAP, which required only capital leases to be recognized on the balance sheet, ASU 2016-02 requires all leases with an initial term greater than one year to be recognized on the balance sheet as a right-of-use ("ROU") asset and a lease liability. We adopted ASU 2016-02 in the first quarter of 2019 by utilizing the modified retrospective transition method through a cumulative-effect adjustment in the beginning of the first quarter of 2019. We elected the package of practical expedients permitted under the transition guidance, which allowed us to carryforward our historical lease classification, our assessment on whether a contract is or contains a lease, and our initial direct costs for any leases that existed prior to the adoption of the new standard. We made an accounting policy election to keep leases with an initial term of 12 months or less off the balance sheet. We have elected the practical expedient the Company will not separate a qualifying contract into its lease and non-lease components. The Company recognizes those lease payments in the Consolidated Statements of Operations on a straight-line basis over the lease term. The most significant impact was the recognition of ROU assets and lease liabilities for operating leases with original terms over 12 months where the Company is the lessee. As a result of the adoption of the new lease standard we recognized ROU assets of $161.6 million , and lease liabilities of $218.0 million , and recorded a cumulative effect adjustment to increase retained earnings of $8.7 million , due to build-to-suit leases and prior deferred gains on sales leaseback transactions. Recent Accounting Pronouncements In August 2018, the FASB issued ASU No. 2018-15, Intangibles-Goodwill and Other-Internal Use Software (Subtopic 350-40 ) ("ASU 2018-15") - Customer's Accounting for Implementation Costs incurred in a Cloud Computing Arrangement that is a Service Contract . ASU 2018-15 reduces the complexity of accounting for costs of implementing a cloud computing service arrangement and aligns the following requirements to capitalize implementation costs: (i) those incurred in a hosting arrangement that is a service contract, and (ii) those incurred to develop or obtain internal-use software, including hosting arrangements that include an internal software license. This amended guidance is first effective for our fiscal year beginning after December 15, 2019 with early adoption permitted. The guidance may be adopted either using the prospective or retrospective approach. We are currently evaluating the impact of this new guidance on our financial position and results of operations.

Business Combinations [Abstract]
Acquisitions	Acquisitions On the Acquisition Date, we completed the acquisition of all outstanding interests in Barteca for total cash consideration of $331.2 million , which represents a purchase price of $325 million plus customary adjustments including payments for cash remaining in the business. Barteca owns and operates two restaurant concepts: Barcelona and bartaco. Barcelona and bartaco restaurant concepts are innovative, with a unique vibe, food, drinks and design. Barcelona serves as a neighborhood Spanish tapas bar with an ever-changing selection of tapas, using both local and seasonal ingredients as well as specialties from Spain and the Mediterranean. Barcelona has a superior Spanish wine program and an award winning selection of wines, with 17 locations in 9 states and the District of Columbia. bartaco combines fresh, upscale street food with a coastal vibe in a relaxed environment and is inspired by a healthy, outdoor lifestyle. bartaco has 21 locations across 13 states, as of June 25, 2019 . The following table summarizes the preliminary fair value of identified assets acquired and liabilities assumed at the Acquisition Date: As of (Amounts in thousands) June 27, 2018 Purchase price $ 331,199 Allocation of purchase price Cash and cash equivalents 6,006 Accounts receivable 3,311 Inventory 2,068 Prepaid expenses and other assets 3,740 Leasehold improvements 34,919 Buildings and improvements 17,967 Furniture, fixtures, and equipment 13,207 Construction in progress 4,340 Other assets 1,421 Intangible assets 185,080 (Unfavorable) leases (785 ) Accounts payable and other liabilities (14,111 ) Financing lease obligations (13,340 ) Deferred taxes (28,147 ) Total fair value of net assets acquired: 215,676 Goodwill $ 115,523 Intangible assets acquired primarily include liquor licenses and bartaco and Barcelona trade names. The fair value of the acquired liquor licenses and trade names are $1.1 million and $183.0 million , respectively. Other intangible assets were valued at approximately $0.2 million . Liquor licenses acquired will be amortized over an estimated useful life of each individual license, which is currently estimated to be one year. Trade names represent intangible assets with indefinite life. As a result of the acquisition, we have recognized approximately $115.5 million of goodwill, of which $104.7 million is deductible for income tax purposes. Goodwill, of which $43.2 million and $72.3 million is attributable to the Barcelona and bartaco reportable segments, respectively, represents the excess of the purchase price over the aggregate fair value of net assets acquired and is related to the benefits expected as a result of the acquisition, including sales, development and growth opportunities. We believe that Barteca's innovative concepts are highly complementary and will provide Del Frisco’s portfolio with significant growth and development opportunities, enabling us to capture market share in the experiential dining segment, while mitigating the effects of seasonality and the risk of economic downturns to our restaurant portfolio. The purchase accounting is complete, and our estimates and assumptions were subject to change during the measurement period (up to one year from the acquisition date). Amounts previously estimated have changed during the measurement period. The changes in estimates included an increase of $4.5 million of buildings and improvements, an increase of $2.0 million of financing lease obligations and a decrease of $0.9 million in accounts payable. We recorded the measurement-period adjustments in the fourth quarter of 2018. Depreciation and interest expenses increased by $0.2 million and $0.1 million , respectively as a result of these measurement-period adjustments. Additionally, deferred tax liabilities increased by $3.1 million with a corresponding change to goodwill in the second quarter of 2019.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments As of June 25, 2019 , we have entered into one derivative instrument designated as a cash flow hedge for risk management purposes. The derivative instrument is used to mitigate our exposure to interest rate fluctuations. Interest Rate Cap During fiscal 2018 , we entered into an interest rate cap with a notional value of $200.0 million and 3.00% per annum strike rate to hedge the variability of the monthly 1-month LIBOR interest payments on a portion of our Term Loan B. The hedged monthly interest payments began on July 31, 2018 and end on the expiration of the interest rate cap on June 30, 2022. Any variability in the 1-month LIBOR interest payment on the Term Loan Facility beyond 3.00% per annum is offset by the net proceeds received upon exercising the interest rate cap. The interest rate cap was designated as a cash flow hedge at inception. The hedge effectiveness for the designated interest rate cap is based on the changes in the interest rate cap’s intrinsic value. Accordingly, we will exclude all the change in the time value of the interest rate cap from the assessment. The excluded component will be amortized over the life of the derivative instrument and recognized in Interest, net of capitalized interest in the Consolidated Statements of Operations. The amount of gains (losses) that are reported in accumulated other comprehensive income (loss) at the reporting date that are expected to be reclassified into earnings within the next 12 months is $0.5 million . Credit Risk We are exposed to credit risk of the counterparty with which we entered into the derivative. This is the risk of the counterparty’s non-performance pursuant to the derivative contract. The risk will continue to exist as long as the derivative is in an asset position, creating a liability for the counterparty. However, the risk is deemed to be minimal as the counterparty has investment grade credit ratings. We will monitor the counterparty’s credit ratings and our market position with the counterparty on an ongoing basis. The interest rate cap does not contain any credit-risk related contingent features. Quantitative Disclosures on Derivative Instruments The following tables present the required quantitative disclosures for our derivative instrument, including its estimated fair values (all estimated using Level 2 inputs) and their financial statement presentation for the fiscal quarters ended June 25, 2019 and June 26, 2018 , respectively.

Debt Disclosure [Abstract]
Long-Term Indebtedness	Long-Term Indebtedness Credit Facilities On June 27, 2018, in connection with the completion of the Barteca Acquisition, we entered into a new credit agreement that provides for (i) a seven year senior secured term loan Term Loan B in aggregate principal amount of $390.0 million bearing interest per annum equal to either a LIBOR or ABR rate, plus an applicable margin, which is equal to 4.75% per annum for LIBOR loans and 3.75% for ABR loans, with the option to maintain or convert base rate loans to LIBOR loans and (ii) five year senior secured revolving credit commitments ("Revolving Loan") in an aggregate principal amount of $50.0 million with the ability to increase the facility by up to an additional $25.0 million with unpaid amounts bearing interest at 3.50% per annum for LIBOR loans and 2.50% per annum for ABR loans. Similar to the term loan, base rate loans may be maintained or converted to LIBOR loans. Rates may be subject to adjustment by reference to the consolidated total leverage ratio, (collectively with the term loans, the "2018 Credit Facility"). Part of the proceeds from the term loans were used to retire the 2012 Credit Facility. On August 6, 2018, we received $97.8 million of proceeds from a public offering of common stock that were used to repay a portion of the $390.0 million of the Term Loan B pursuant to an existing prepayment option. On August 27, 2018 we amended ("The First Amendment") Term Loan B ("Amended Term Loan B"). The First Amendment amends the 2018 Credit Facility, to, among other things, completely re-syndicate the Amended Term Loan B and provide the Company with additional term loans ("Additional Term Loans") in an aggregate principal amount of $18.0 million . The First Amendment also amended the 2018 Credit Facility to increase the interest rate applicable to the Additional Term Loans and the existing term loans outstanding under the 2018 Credit Facility to, at our option, a rate per annum equal to either a LIBOR or ABR rate, plus an applicable margin, which is equal to 6.00% for LIBOR loans and 5.00% for ABR loans. On February 26, 2019, we entered into a joinder agreement with JPMorgan Chase Bank, N.A., as the incremental term lender and JPMorgan Chase Bank, N.A. as the administrative agent (the “Joinder Agreement”). The Joinder Agreement modifies the 2018 Credit Facility and provides the Company with incremental term loan commitments in a principal amount equal to $25.0 million . The Company drew the full amount of the incremental term loans on the date of the Joinder Agreement and received net proceeds of approximately $23.1 million . The Company used the net proceeds of the incremental term loans to repay a portion of the outstanding amounts under the 2018 Credit Facility. Since the repayment does not reduce the commitments under the 2018 Credit Facility, the transaction expanded the Company’s sources of liquidity without increasing leverage at this time. On June 17, 2019, we entered into an amendment (the “Second Amendment”) to the 2018 Credit Facility to increase the percentage of Projected EBITDAR Margin that may be included when determining Consolidated EBITDAR for purposes of calculating the Financial Covenant (as defined in the 2018 Credit Facility). As of June 25, 2019 , $32.0 million under the Revolving Loan was outstanding (excluding amounts reserved for letters of credit in the amount of $1.6 million ). As of December 25, 2018 , $23.7 million under the Revolving Loan, was outstanding (excluding amounts reserved for letters of credit in the amount of $1.6 million ). The unpaid Revolving Loan amounts bear interest at 3.50% per annum for LIBOR loans and 2.50% per annum for ABR loans. As of June 25, 2019 , the Revolving Loan unused commitment fee was 0.50% . The principal amount of the Revolving Loan is due and payable on June 27, 2023. As of June 25, 2019 , $332.8 million was outstanding under the Amended Term Loan B. Interest on the Amended Term Loan B accrues at a rate per annum equal to either a LIBOR or ABR rate, plus an applicable margin, which is equal to 6.00% for LIBOR loans and 5.00% for ABR loans. The Interest Rate Cap Agreement, which has a notional value of $200.0 million and 3.00% per annum strike rate to hedge the variability of the monthly 1-month LIBOR interest payments on a portion of our Term Loan B, mitigates the risk of an increase in the LIBOR rate in effect on the Amended Term Loan B. See Note 6 , Derivative Financial Instruments for further discussion. As of June 25, 2019 , the applicable interest rate on the Amended Term Loan B was 8.50% . The Amended Term Loan B is payable in equal quarterly installments of $0.8 million . The outstanding principal of the Amended Term Loan B is due and payable on June 27, 2025. Amounts outstanding under the 2018 Credit Facility are guaranteed by Del Frisco's and certain of the subsidiaries of Del Frisco’s (collectively, the "Loan Parties"). The 2018 Credit Facility is secured by a first priority security interest in substantially all of the assets of the Loan Parties. The 2018 Credit Facility agreement contains certain representations, warranties and affirmative covenants and financial covenants, including a maximum ratio of total indebtedness to EBITDAR, as defined in the credit agreement governing the credit facility. The total indebtedness to EBITDAR calculation is applicable only when we are over 25% drawn on the Revolver at the end of the reporting period. In addition, the 2018 Credit Facility agreement contains covenants restricting certain corporate actions, including asset dispositions, acquisitions, the payment of dividends, the incurrence of indebtedness and providing financing or other transactions with affiliates. Loan Against the Investments in Deferred Compensation Plan On July 12, 2017, we executed an agreement to borrow against the investments in our deferred compensation plan to pay out funds due to plan participants instead of using operating cash flows. The loan does not have an expiration date or defined payment terms, and accrues interest at a rate of 1% , net of the 4% that is earned by the investments being loaned against. As of June 25, 2019 and December 25, 2018 there was $3.6 million and $3.8 million of outstanding borrowings on this loan, respectively. Long-Term Indebtedness Summary As of June 25, 2019 and December 25, 2018 , long-term debt consisted of the following: As of (Amounts in thousands) June 25, 2019 December 25, 2018 Amended Term Loan B $ 332,803 $ 309,417 Revolving Loan 32,000 23,700 Loan Against the Investments in Deferred Compensation Plan 3,577 3,820 Net discount (13,065 ) (12,107 ) Deferred financing costs (1,207 ) (994 ) Long-term debt 354,108 323,836 Less current portion (3,353 ) (3,100 ) Total long-term debt, net $ 350,755 $ 320,736

Leases

Leases [Abstract]
Leases	Leases We adopted ASU 2016-02 in the first quarter of 2019 by utilizing the modified retrospective transition method through a cumulative-effect adjustment in the beginning of the first quarter of 2019. We elected the package of practical expedients permitted under the transition guidance, which allowed us to carryforward our historical lease classification, our assessment on whether a contract is or contains a lease, and our initial direct costs for any leases that existed prior to the adoption of the new standard. We made an accounting policy election to keep leases with an initial term of 12 months or less off the balance sheet. We have elected the practical expedient the Company will not separate a qualifying contract into its lease and non-lease components. The Company recognizes those lease payments in the Consolidated Statements of Operation on a straight-line basis over the lease term. The most significant impact was the recognition of ROU assets and lease liabilities for operating leases with original terms over 12 months where the Company is the lessee. Upon adoption of Topic 842 during the first quarter of 2019 we recognized ROU of $161.6 million , and lease liabilities of $218.0 million , and recorded a cumulative effect adjustment to increase retained earnings of $8.7 million , due to build-to-suit leases and prior deferred gains on sales leaseback transactions. We currently lease all of our restaurants. We lease certain facilities under noncancelable operating leases and have several obligations under finance leases, with terms expiring between 2019 and 2039 . The operating and finance leases have renewal options ranging from 5 to 20 years, which are exercisable at our 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. The majority of our leases provide for minimum annual rents with some containing percentage-of-sales rent provisions, against which the minimum rent may be applied. The majority of our leases also provide for rent escalation clauses, contingent rental expense, and/or tenant improvement allowances. Minimum rental payments under operating leases are recognized on a straight-line basis over the expected term of the lease, which includes optional renewal periods that are reasonably certain to be exercised and where failure to exercise such renewal options would result in an economic penalty to us. For the Company's operating and finance leases, the lease liability is initially and subsequently measured at the present value of the unpaid lease payments at the lease commencement date. Key estimates and judgments include how the Company determines (i) the discount rate it uses to discount the unpaid lease payments to present value, (ii) lease term and (iii) lease payments. Topic 842 requires a lessee to discount its unpaid lease payments using the interest rate implicit in the lease or, if that rate cannot be readily determined, its incremental borrowing rate ("IBR"). Generally, the Company cannot determine the interest rate implicit in the lease and therefore uses the IBR as a discount rate for its leases. The IBR reflects the rate of interest the Company would pay on a collateralized basis to borrow an amount equal to the lease payments under similar terms. To estimate our specific incremental borrowing rates over various tenors (ranging from 3 -year through 30 -years), a comparable market yield curve consistent with our credit quality was calibrated to our outstanding debt instruments. The lease term for all of the Company's leases includes the noncancellable period of the lease plus any additional periods covered by an option to extend the lease that is reasonably certain to be executed by the Company. Lease payments included in the measurement of the lease liability comprise fixed payments owed over the lease term, fixed non-lease component payments, variable lease payments that depend on an index or rate, and the renewal option if it is reasonably certain the Company will exercise the option. As part of the lease agreements the Company is also responsible for payments regarding non-lease components (common area maintenance, operating expenses, etc.) and most of these payments are variable costs; however, some leases have fixed operating or common area maintenance expenses so these leases with fixed non-lease component payments were included as part of the lease liabilities. The ROU asset is initially measured at cost, which comprises the initial amount of lease liability adjusted for lease payments made at or before the lease commencement date, plus any initial direct costs incurred less any lease incentives received. For the Company's operating leases, the ROU asset is subsequently measured throughout the lease term at the carrying amount of the lease liability, plus initial direct costs, and adjusted for any prepaid or accrued lease payments, less the unamortized balance of lease incentives received.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The effective income tax rate for the 13 weeks ended June 25, 2019 was 29.3% , compared to 61.1% for the 13 weeks ended June 26, 2018 . The effective income tax rate for the 26 weeks ended June 25, 2019 was 13.5% , compared to 61.1% for the 26 weeks ended June 26, 2018 . For the 26 weeks ended June 25, 2019 , the factors that cause the effective tax rates to vary from the federal statutory rate of 21% were primarily the change to the valuation allowance, the effect of certain permanent differences and the impact of the FICA tip deduction addback. For the 26 weeks ended June 26, 2018 , the factors causing the effective tax rates to vary from the federal statutory rate of 21% include the impact of the FICA tip and other credits, partially offset by state income taxes and certain non-deductible expenses. The Company assesses the available positive and negative evidence at each balance sheet date to determine whether sufficient future taxable income will be generated to permit the use of existing deferred tax assets. The purpose of this analysis is to assess whether it is more likely than not that some or all of our deferred tax assets will not be realized. Significant judgment is required in estimating valuation allowances for deferred tax assets and in making this determination, we consider all available positive and negative evidence and make certain assumptions. The realization of a deferred tax asset ultimately depends on the existence of sufficient taxable income in the applicable carryback or carryforward periods. To the extent we generate sufficient taxable income in the future to fully utilize the tax benefits of the net deferred tax assets on which a valuation allowance was recorded; our effective tax rate may decrease as the valuation allowance is reversed. During fiscal 2018, the Company entered a three year cumulative loss position and established a valuation allowance against deferred tax assets for which it is more likely than not that the deferred tax assets will not be realized.

Fair Value Measurement

Fair Value Measurement	6 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurement	Fair Value Measurement Under GAAP, we are 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 our 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. Fair Value of Debt and Other Financial Instruments Debt is recorded at carrying value. The fair value of long-term debt is based on market prices that generally are observable for similar liabilities at commonly quoted intervals and is considered a Level 2 fair value measurement. The estimated fair value of debt (including current portion) is $355.8 million and $303.7 million and the carrying amount is $354.1 million and $323.8 million as of June 25, 2019 and December 25, 2018 , respectively. At June 25, 2019 , the carrying values of other financial instruments such as cash and cash equivalents, receivables and accounts payable approximate fair value due to their short-term nature. Recurring Fair Value Measurements The following table presents our financial assets and liabilities measured at fair value on a recurring basis at June 25, 2019 and December 25, 2018 , respectively:  Fair Value Measurements (Amounts in thousands) Level June 25, 2019 December 25, 2018 Financial assets (liabilities): Carrying Amount Fair Value Carrying Amount Fair Value Deferred compensation plan investments (included in Other assets) 2 $ 15,035 $ 15,035 $ 13,556 $ 13,556 Deferred compensation plan liabilities (included in Other liabilities) 2 (9,520 ) (9,520 ) (8,059 ) (8,059 ) Interest rate cap agreement assets (included in Other current assets) 2 132 132 1,075 1,075 There were no transfers among levels within the fair-value hierarchy during the first two quarters of fiscal 2019 and fiscal 2018 . The following methods and assumptions were used to estimate the fair value of each class of financial instruments: • The measurement of the fair value of derivative assets and liabilities is based on market prices that generally are observable for similar assets and liabilities at commonly quoted intervals and is considered a Level 2 fair value measurement. Derivative assets and liabilities that have maturity dates equal to or less than twelve months from the balance sheet date are included in prepaid and other current assets and other accrued liabilities, respectively. Derivative assets and liabilities that have maturity dates greater than twelve months from the balance sheet date are included in deposits and other assets and other long-term liabilities, respectively. See Note 2 Summary of Significant Accounting Policies of our 2018 10-K for additional information on our derivative instruments and related Company policies.

Segment Reporting [Abstract]
Segment Reporting	Segment Reporting We operate the Double Eagle, Barcelona, bartaco, and Grille brands as operating segments. The restaurant 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 we do not rely on any major customers as a source of sales. The restaurant concepts also possess similar economic characteristics, resulting in similar long-term expected financial performance characteristics. However, Double Eagle restaurants typically have higher revenues, driven by their larger physical presence and higher average check. The Double Eagle, Barcelona, bartaco, and 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 tables present information about reportable segments:  13 Weeks Ended June 25, 2019 (Amounts in thousands) Double Eagle Barcelona bartaco Grille Corporate Consolidated Revenues $ 49,423 $ 21,096 $ 28,227 $ 32,941 $ — $ 131,687 Restaurant-level EBITDA 11,505 5,208 6,901 4,679 — 28,293 Capital expenditures 4,420 2,583 4,942 1,408 91 13,444 Property and equipment, gross 160,746 41,459 59,646 132,785 4,199 398,835  13 Weeks Ended June 26, 2018 (Amounts in thousands) Double Eagle Barcelona bartaco Grille Corporate Consolidated Revenues $ 43,471 $ — $ — $ 32,247 $ — $ 75,718 Restaurant-level EBITDA 11,130 — — 5,048 — 16,178 Capital expenditures 18,420 — — 6,171 106 24,697 Property and equipment, gross 134,631 — — 122,909 5,324 262,864  26 Weeks Ended June 25, 2019 (Amounts in thousands) Double Eagle Barcelona bartaco Grille Corporate Consolidated Revenues $ 99,398 $ 38,287 $ 49,109 $ 65,274 $ — $ 252,068 Restaurant-level EBITDA 21,930 8,675 11,317 9,070 — 50,992 Capital expenditures 7,512 4,409 9,781 2,411 528 24,641 Property and equipment, gross 160,746 41,459 59,646 132,785 4,199 398,835  26 Weeks Ended June 26, 2018 (Amounts in thousands) Double Eagle Barcelona bartaco Grille Corporate Consolidated Revenues $ 87,425 $ — $ — $ 61,639 $ — $ 149,064 Restaurant-level EBITDA 22,176 — — 8,380 — 30,556 Capital expenditures 28,206 — — 8,154 (249 ) 36,111 Property and equipment, gross 134,631 — — 122,909 5,324 262,864 In addition to using consolidated results in evaluating our performance and allocating our resources, our chief operating decision maker uses restaurant-level EBITDA, which is not a measure defined by GAAP at both the segment and consolidated level. At the consolidated level, this non-GAAP operating measure is useful to both management and investors because it represents one means of gauging the overall profitability of our recurring and controllable core restaurant operations. This measure is not, however, indicative of our overall results, nor does restaurant-level profit accrue directly to the benefit of stockholders, primarily due to the exclusion of corporate-level expenses. Restaurant-level EBITDA on a consolidated basis should not be considered a substitute for, or superior to, operating income loss, which is calculated in accordance with GAAP, and the reconciliations to operating income set forth below should be carefully evaluated. We define restaurant-level EBITDA as operating income before pre-opening costs, general and administrative costs, donations, consulting project costs, acquisition costs, reorganization severance costs, lease termination and closing 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 costs are only included in our consolidated financial results as they are generally not specifically identifiable to individual operating segments as these costs relate to supporting all of our restaurant operations and the extension of our concepts into new markets. Donations, consulting project costs, acquisition costs and reorganization severance costs are excluded because they are not related to the health of ongoing operations. Lease termination and closing costs and depreciation and amortization are excluded because they are not ongoing controllable cash expenses, and they are not related to the health of ongoing operations. Property and equipment is the only balance sheet measure used by our chief operating decision maker in allocating resources.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies We are subject to various claims, possible legal actions, and other matters arising out of the normal course of business. While it is not possible to predict the outcome of these issues, management is of the opinion that adequate provision for potential losses has been made in the accompanying condensed consolidated financial statements and that the ultimate resolution of these matters will not have a material adverse effect on our consolidated financial position, results of operations or cash flows. Litigation Related to the Merger On July 25, 2019, a complaint was filed, captioned Sabatini v. Del Frisco’s Restaurant Group, Inc. et al., Case No. 1:19-cv-01385-LPS (the “Sabatini Complaint”). The Sabatini Complaint generally alleges that the Company and the members of its Board of Directors violated Sections 14(a) and 20(a) of the Exchange Act and Rule 14a-9 promulgated thereunder by omitting material information from the Proxy Statement rendering it false and misleading and seeks, among other things, an injunction against the Merger, or in the event the Merger is consummated, rescission and rescissory damages, additional disclosure of facts in the Proxy Statement relating to the Merger, a declaration from the court that the defendants violated federal securities laws, and costs (including attorneys’ and experts’ fees). On July 29, 2019, a complaint was filed, captioned Stein v. Del Frisco’s Restaurant Group, Inc. et al., Case No. 1:19-cv-01412-LPS (the “Stein Complaint”). The Stein Complaint generally alleges that the Company and the members of its Board of Directors violated Sections 14(a) and 20(a) of the Exchange Act and Rule 14a-9 promulgated thereunder by omitting material information from the Proxy Statement rendering it false and misleading and seeks, among other things, an injunction against the Merger, or in the event the Merger is consummated, rescission and rescissory damages, additional disclosure of facts in the Proxy Statement relating to the Merger, a declaration from the court directing the defendants to account to plaintiff for all damages suffered as a result of their wrongdoing, and costs and disbursements (including attorneys’ and experts’ fees and expenses). On August 2, 2019, a complaint was filed, captioned Kyle T. Karmazyn v. Del Frisco’s Restaurant Group, Inc., et al. , Case No. 1:19-cv-07193 (LAP) (the “Karmazyn Complaint”). The Karmazyn Complaint alleges generally that the Company and the members of its Board of Directors violated Sections 14(a) and 20(a) of the Exchange Act and Rule 14a-9 promulgated thereunder by omitting material information from the Proxy Statement and seeks, among other things, an injunction against the Merger unless and until the Company makes additional disclosure of facts in the Proxy Statement relating to the Merger, the court to direct the defendants to account to plaintiff for all alleged damages sustained as a result of their alleged wrongdoing, and costs and disbursements (including attorneys’ and experts’ fees and expenses). Credit Commitments At June 25, 2019 and December 25, 2018 , we had outstanding letters of credit of $1.6 million , which were drawn on our 2018 Credit Facility (see Note 7 , Long-Term Indebtedness) . The letters of credit typically act as a guarantee of payment to certain third parties in accordance with specified terms and conditions.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business and Basis of Presentation	Business and Basis of Presentation As of June 25, 2019 , Del Frisco’s Restaurant Group, Inc. ("we," "us," "our," “Del Frisco’s” or the “Company”) owned and operated 78 restaurants under the concept names of Del Frisco’s Double Eagle Steakhouse (“Double Eagle”), Barcelona Wine Bar (“Barcelona”), bartaco, and Del Frisco’s Grille (“Grille”). Of the 78 restaurants we operated at the end of the period covered by this report, there were 16 Double Eagle restaurants, 17 Barcelona restaurants, 21 bartaco restaurants, and 24 Grille restaurants in operation in 17 states and the District of Columbia. Recent Developments On June 27, 2018 (“Acquisition Date”), we completed the acquisition of all outstanding interests in Barteca Holdings, LLC ("Barteca Acquisition"), a Delaware limited liability company, and its subsidiaries (“Barteca”) for total cash consideration of $331.2 million , which represents a purchase price of $325 million plus customary adjustments including payments for cash remaining in the business. In connection with the completion of the Barteca Acquisition, we entered into a new credit agreement that provides for (i) senior secured term loans in an aggregate principal amount of $390.0 million (“Term Loan B”) and (ii) senior secured revolving credit commitments in an aggregate principal amount of $50.0 million (“Revolving Loan,” and, collectively with the term loans, the “2018 Credit Facility”). See Note 7 , Long-Term Debt in the notes to our condensed consolidated financial statements for information regarding our credit facility. On August 1, 2018, we entered into an underwriting agreement with certain underwriters with respect to (i) the sale by the Company of 11,250,000 shares of the Company’s common stock, par value $0.001 per share, to the underwriters and (ii) the grant by the Company to the underwriters of an option (the “Option”) to purchase up to 1,687,500 additional shares of the Company’s common stock (together, the “Shares”). The sale of the Shares, including the exercise in full of the Option, closed on August 6, 2018. The total proceeds of $97.8 million from the public offering of common stock were used to repay a portion of Term Loan B. See Note 7 , Long-Term Debt in the notes to our condensed consolidated financial statements. On August 27, 2018 we amended (the “First Amendment”) Term Loan B (“Amended Term Loan B”). The First Amendment amends the 2018 Credit Facility, to, among other things, provide the Company with additional term loans (“Additional Term Loans”) in an aggregate principal amount of $18.0 million . The First Amendment also amended the 2018 Credit Facility to increase the interest rate applicable to the Additional Term Loans and the existing term loans outstanding under the 2018 Credit Facility to, at our option, a rate per annum equal to either a LIBOR or a base rate, plus an applicable margin, which is equal to 6.00% for LIBOR rate loans and 5.00% for base rate loans. See Note 7 , Long-Term Debt in the notes to our condensed consolidated financial statements for information regarding our amended credit facility. On September 21, 2018, we sold all of the outstanding equity interests in our Sullivan’s Steakhouse business (“Sullivan’s") to Sullivan’s Holding LLC, a Delaware limited liability company and affiliate of Romano’s Macaroni Grill, for the total gross proceeds of approximately $32 million , subject to customary adjustments for inventory and cash. See Note 3 , Dispositions in the notes to our condensed consolidated financial statements for information regarding discontinued operations. On February 26, 2019, we entered into a joinder agreement with JPMorgan Chase Bank, N.A., as the incremental term lender and JPMorgan Chase Bank, N.A. as the administrative agent (the “Joinder Agreement”). The Joinder Agreement modifies the 2018 Credit Facility and provides the Company with incremental term loan commitments in a principal amount equal to $25.0 million . The Company drew the full amount of the incremental term loans on the date of the Joinder Agreement and received net proceeds of approximately $23.1 million . The Company used the net proceeds of the incremental term loans to repay a portion of the outstanding amounts under the 2018 Credit Facility. Since the repayment does not reduce the commitments under the 2018 Credit Facility, the transaction expanded the Company’s sources of liquidity without increasing leverage at this time. See Note 7 , Long-Term Debt in the notes to our condensed consolidated financial statements. On June 17, 2019, we entered into an amendment (the “Second Amendment”) to the 2018 Credit Facility to increase the percentage of Projected EBITDAR Margin that may be included when determining Consolidated EBITDAR for purposes of calculating the Financial Covenant (as defined in the 2018 Credit Facility). See Note 7 , Long-Term Debt in the notes to our condensed consolidated financial statements. On June 23, 2019, we entered into a definitive agreement to be acquired by affiliates of L Catterton, a consumer-focused private equity firm with over $15 billion of equity capital across six fund strategies in 17 offices globally. Under the terms of the agreement, affiliates of L Catterton will acquire all outstanding shares of the Company’s common stock for a total value of approximately $650 million . Company stockholders will receive $8.00 in cash per share. The Agreement and Plan of Merger, dated as of June 23, 2019, by and among the Company, Harlan Parent, Inc. and Harlan Merger Sub, Inc. was filed as an exhibit to our Current Report on Form 8-K filed with the SEC on June 24, 2019. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information. Accordingly, they do not include all the information and disclosures required by GAAP for complete financial statements. Operating results for the 13 weeks and 26 weeks ended June 25, 2019 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2019 . In the opinion of management, the unaudited condensed consolidated financial statements include all adjustments, consisting of normal recurring adjustments, considered necessary for a fair presentation. These unaudited condensed consolidated financial statements and related notes should be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for the fiscal year ended December 25, 2018 filed with the SEC on March 11, 2019 (the “2018 10-K”). The results of Sullivan's operations have been presented as discontinued operations for the 13 weeks and and 26 weeks ended June 26, 2018 . See Note 3 , Dispositions in the notes to our condensed consolidated financial statements for information regarding discontinued operations. We operate on a 52- or 53-week fiscal year ending the last Tuesday in December. Beginning in fiscal 2018, we changed to a fiscal quarter calendar where each quarter contains 13 weeks, other than in a 53-week year where the last quarter of the year will contain 14 weeks. Fiscal 2019 will be a 53-week fiscal year, fiscal 2018 was a 52-week fiscal year. We believe that a reporting basis comprised of four equal 13-week quarters is a more typical reporting format comparable to most companies in the restaurant industry and is easier to understand for our investors.
Accounting Estimates	Accounting Estimates The preparation of the unaudited condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. We base our estimates on historical experience and on various assumptions that are believed to be reasonable under the circumstances at the time. Actual amounts may differ from those estimates.
Recent Adopted and Recent Accounting Pronouncements	Recently Adopted Accounting Pronouncements In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) ("ASU 2016-02"). which requires a lessee to recognize assets and liabilities for leases with lease terms of more than 12 months. The recognition, measurement and presentation of expenses and cash flows arising from a lease by a lessee will primarily depend on its classification as a finance (formerly capital) or operating lease. However, unlike previous GAAP, which required only capital leases to be recognized on the balance sheet, ASU 2016-02 requires all leases with an initial term greater than one year to be recognized on the balance sheet as a right-of-use ("ROU") asset and a lease liability. We adopted ASU 2016-02 in the first quarter of 2019 by utilizing the modified retrospective transition method through a cumulative-effect adjustment in the beginning of the first quarter of 2019. We elected the package of practical expedients permitted under the transition guidance, which allowed us to carryforward our historical lease classification, our assessment on whether a contract is or contains a lease, and our initial direct costs for any leases that existed prior to the adoption of the new standard. We made an accounting policy election to keep leases with an initial term of 12 months or less off the balance sheet. We have elected the practical expedient the Company will not separate a qualifying contract into its lease and non-lease components. The Company recognizes those lease payments in the Consolidated Statements of Operations on a straight-line basis over the lease term. The most significant impact was the recognition of ROU assets and lease liabilities for operating leases with original terms over 12 months where the Company is the lessee. As a result of the adoption of the new lease standard we recognized ROU assets of $161.6 million , and lease liabilities of $218.0 million , and recorded a cumulative effect adjustment to increase retained earnings of $8.7 million , due to build-to-suit leases and prior deferred gains on sales leaseback transactions. Recent Accounting Pronouncements In August 2018, the FASB issued ASU No. 2018-15, Intangibles-Goodwill and Other-Internal Use Software (Subtopic 350-40 ) ("ASU 2018-15") - Customer's Accounting for Implementation Costs incurred in a Cloud Computing Arrangement that is a Service Contract . ASU 2018-15 reduces the complexity of accounting for costs of implementing a cloud computing service arrangement and aligns the following requirements to capitalize implementation costs: (i) those incurred in a hosting arrangement that is a service contract, and (ii) those incurred to develop or obtain internal-use software, including hosting arrangements that include an internal software license. This amended guidance is first effective for our fiscal year beginning after December 15, 2019 with early adoption permitted. The guidance may be adopted either using the prospective or retrospective approach. We are currently evaluating the impact of this new guidance on our financial position and results of operations.
