Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation Chuy’s Holdings, Inc. (the “Company” or “Chuy’s”) develops and operates Chuy’s restaurants throughout the United States. Chuy’s is a fast-growing, full-service restaurant concept offering a distinct menu of authentic, freshly-prepared Mexican and Tex-Mex inspired food. As of September 30, 2018 , the Company operated 98 restaurants in 19 states. In the opinion of management, the accompanying unaudited condensed consolidated financial statements and the related notes reflect all adjustments, consisting only of normal recurring adjustments, necessary to present fairly the Company’s financial position, results of operations and cash flows for the periods presented. The unaudited condensed consolidated financial statements have been prepared in accordance with Generally Accepted Accounting Principles (“GAAP”), except that certain information and notes have been condensed or omitted pursuant to rules and regulations of the Securities and Exchange Commission (the “SEC”). Results for interim periods are not necessarily indicative of the results that may be expected for the full fiscal year. The unaudited condensed consolidated financial statements should be read in conjunction with consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017 . The accompanying condensed consolidated balance sheet as of December 31, 2017 , has been derived from our audited consolidated financial statements. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect certain reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses for the period. Actual results could differ from those estimates. The Company operates on a 52- or 53- week fiscal year that ends on the last Sunday of the calendar year. Each quarterly period has 13 weeks, except for a 53-week year when the fourth quarter has 14 weeks. Our 2018 fiscal year consists of 52 weeks and our 2017 fiscal year consisted of 53 weeks.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements Leases In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-02, "Leases (Topic 842)." This update requires a lessee to recognize on the balance sheet the right-of-use assets and lease liabilities for leases with a lease term of more than twelve months. This update also requires additional disclosures about the amount, timing, and uncertainty of cash flows arising from leases. This ASU is effective for interim and annual periods beginning after December 15, 2018 and requires a modified retrospective approach to adoption for leases existing at, or entered into after the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. In July 2018, the FASB issued ASU 2018-11, "Leases (Topic 842) - Targeted Improvements," which provides another transition method that allows entities to apply the new lease standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. This transition method option is in addition to the existing transition method of using a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. We anticipate electing the transition method option to apply the standard as of the effective date and therefore, we will not apply the standard to the comparative periods presented in our financial statements. We also anticipate taking advantage of the transition package of three practical expedients permitted within the standard, which among other things, allows the carryforward of historical lease classifications, and evaluating other practical expedients available and policy elections. We had operating leases with remaining rental payments of approximately $404.7 million as of December 31, 2017. The discounted minimum remaining rental payments will be the starting point for determining the assets and liabilities for the rights and obligations created by those leases. While the Company is still evaluating the impact on its consolidated financial statements, we expect the adoption of this standard will have a significant impact on the Company’s consolidated balance sheet as we will recognize the right-of-use assets and liabilities for current operating leases. Our calculations of the impact are dependent on a number of key assumptions including discount rates and other factors such as the number of leases commenced, renewed or expired as of effective date of the guidance. We do not expect a significant impact on the consolidated statement of income or cash flows and overall liquidity. In preparation for the adoption of the guidance, the Company will implement controls and key systems changes to enable the preparation of financial information. Revenue Recognition The Company adopted ASU 2014-09, "Revenue with Contracts from Customers (Topic 606)," in the first quarter of 2018. The comparative financial information has not been restated and continues to be reported under the accounting standards in effect for those periods. The adoption of this ASU was immaterial to the Company's consolidated financial statements. The Company's revenue is mainly comprised of food and beverage sales. Proceeds from the sale of gift cards are recorded as deferred revenue at the time of sale and recognized as revenue upon redemption by the customer. ASU 2014-09 does not have an impact on revenue recognition related to food and beverage sales. However, it requires gift card breakage to be recognized as revenue proportionate to the pattern of gift card redemptions. Under the previous guidance, the Company determined breakage when the likelihood of redemption of a gift card by a customer was remote. The Company continues to record gift card breakage as a component of revenue. The Company reviewed all other recently issued accounting pronouncements and concluded that they were either not applicable or not expected to have a significant impact on the Company's consolidated financial statements.

Earnings Per Share [Abstract]
Net Income Per Share	Net (Loss) Income Per Share The number of shares and net (loss) income per share data for all periods presented are based on the historical weighted-average shares of common stock outstanding. Basic net (loss) income per share of the Company's common stock is computed by dividing net (loss) income by the weighted-average number of shares of common stock outstanding for the period. Diluted net (loss) income per share of the Company's common stock is computed on the basis of the weighted-average number of shares of common stock plus the effect of dilutive potential shares of common stock equivalents outstanding during the period using the treasury stock method for dilutive options and deferred shares (these deferred shares were granted under the Chuy's Holdings, Inc. 2012 Omnibus Equity Incentive Plan (the "2012 Plan"), and are referred to herein as "restricted stock units"). For the thirteen weeks ended September 30, 2018 and September 24, 2017 , there were approximately 1,300 and 100,000 shares, respectively, of common stock equivalents that were excluded from the calculation of diluted net (loss) income per share because their inclusion would have been anti-dilutive. For the thirty-nine weeks ended September 30, 2018 and September 24, 2017 , there were approximately 2,600 and 32,000 shares, respectively, of common stock equivalents that were excluded from the calculation of diluted net (loss) income per share because their inclusion would have been anti-dilutive. The computation of basic and diluted (loss) income per share is as follows: Thirteen Weeks Ended Thirty-Nine Weeks Ended September 30, 2018 September 24, 2017 September 30, 2018 September 24, 2017 BASIC Net (loss) income $ (7,510 ) $ 3,195 $ 2,129 $ 13,074 Weighted-average common shares outstanding 16,948,701 16,905,705 16,940,777 16,886,743 Basic net (loss) income per common share $ (0.44 ) $ 0.19 $ 0.13 $ 0.77 DILUTED Net (loss) income $ (7,510 ) $ 3,195 $ 2,129 $ 13,074 Weighted-average common shares outstanding 16,948,701 16,905,705 16,940,777 16,886,743 Dilutive effect of stock options and restricted stock units 165,489 81,089 140,594 111,570 Weighted-average of diluted shares 17,114,190 16,986,794 17,081,371 16,998,313 Diluted net (loss) income per common share $ (0.44 ) $ 0.19 $ 0.12 $ 0.77

Stock-Based Compensation	Stock-Based Compensation The Company has outstanding awards under the Chuy's Holdings, Inc. 2006 Stock Option Plan (the "2006 Plan") and the 2012 Plan. The 2006 Plan was terminated by the board effective July 27, 2012, and no further awards may be granted under the plan after such date. However, the termination of the 2006 Plan did not affect outstanding awards granted. Options granted under these plans vest over five years from the date of grant and have a maximum term of 10 years. Restricted stock units granted under the 2012 Plan vest over four to five years from the date of grant. As of September 30, 2018 , a total of 496,379 shares of common stock are reserved and remain available for issuance under the 2012 Plan. Stock-based compensation expense recognized in the accompanying condensed consolidated income statements was approximately $811,000 and $747,000 for the thirteen weeks ended September 30, 2018 and September 24, 2017 , respectively, and approximately $2,368,000 and $2,102,000 for the thirty-nine ended September 30, 2018 and September 24, 2017 , respectively. Stock Options A summary of stock-based compensation activity related to stock options for the thirty-nine weeks ended September 30, 2018 are as follows: Shares Weighted Average Exercise Price Weighted Average Remaining Contractual Term (Years) Aggregate Intrinsic Value Outstanding at December 31, 2017 274,110 $ 19.54 Exercised (25,745 ) 17.64 Forfeited (1,043 ) 31.59 Outstanding at September 30, 2018 247,322 $ 19.69 3.44 $ 1,907 Exercisable at September 30, 2018 245,977 $ 19.63 3.43 $ 1,906 The aggregate intrinsic value in the table above is obtained by subtracting the exercise price from the estimated fair value of the underlying common stock as of September 30, 2018 and multiplying this result by the related number of options outstanding and exercisable at September 30, 2018 . The estimated fair value of the common stock as of September 30, 2018 used in the above calculation was $26.25 per share, the closing price of the Company’s common stock on September 28, 2018, the last trading day of the third quarter. The total intrinsic value of options exercised during the thirty-nine weeks ended September 30, 2018 was approximately $286,000 . The fair value of options vested during the thirty-nine weeks ended September 30, 2018 was approximately $260,000 . There was approximately $8,000 of total unrecognized compensation expense related to options granted under the 2006 Plan and the 2012 Plan as of September 30, 2018 . This expense will be recognized ratably over the next year. Restricted Stock Units A summary of stock-based compensation activity related to restricted stock units for the thirty-nine weeks ended September 30, 2018 are as follows: Shares Weighted Average Fair Value Weighted Outstanding at December 31, 2017 258,486 $ 29.64 Granted 219,772 25.76 Vested (94,395 ) 30.87 Forfeited (9,007 ) 27.66 Outstanding at September 30, 2018 374,856 $ 27.10 2.91 The fair value of the restricted stock units is the quoted market value of our common stock on the date of grant. As of September 30, 2018 , total unrecognized stock-based compensation expense related to non-vested restricted stock units was approximately $8.3 million , which is expected to be recognized ratably over the next five years.

Debt Disclosure [Abstract]
Long-Term Debt	Long-Term Debt Revolving Credit Facility On November 30, 2012, the Company entered into a $25.0 million Revolving Credit Facility with Wells Fargo Bank, National Association. On October 30, 2015, the Company entered into an amendment to its Revolving Credit Facility to, among other things, (1) extend the maturity date of the Revolving Credit Facility to October 30, 2020 from November 30, 2017 and (2) revise the applicable margins and leverage ratios that determine the commitment fees and interest rates payable by the Company under the Revolving Credit Facility. Under the Company's Revolving Credit Facility, the Company may request to increase the size of the Revolving Credit Facility by up to an additional $25.0 million , in minimum principal amounts of $5.0 million or the remaining amount of the $25.0 million if less than $5.0 million (the "Incremental Revolving Loan"), which Incremental Revolving Loan will be effective after 10 days written notice to the agent. In the event that any of the lenders fund the Incremental Revolving Loan, the terms and provisions of the Incremental Revolving Loan will be the same as under the Company's Revolving Credit Facility. Borrowings under the Revolving Credit Facility generally bear interest at a variable rate based upon the Company's election, of (i) the base rate (which is the highest of prime rate, federal funds rate plus 0.5% or one month LIBOR plus 1.0% ), or (ii) LIBOR, plus, in either case, an applicable margin based on the Company's consolidated total lease adjusted leverage ratio (as defined in the Revolving Credit Facility agreement). The Revolving Credit Facility also requires payment for commitment fees that accrue on the daily unused commitment of the lender at the applicable margin, which varies based on the Company's consolidated total lease adjusted leverage ratio. The Revolving Credit Facility also requires compliance with a fixed charge coverage ratio, a lease adjusted leverage ratio and certain non-financial covenants. The Revolving Credit Facility also places certain restrictions on the payment of dividends and distributions. Under the Revolving Credit Facility, the Company may declare and make dividend payments so long as (i) no default or event of default has occurred and is continuing or would result therefrom and (ii) immediately after giving effect to any such dividend payment, on a pro forma basis, the lease adjusted leverage ratio does not exceed 3.50 to 1.00. The obligations under the Company’s Revolving Credit Facility are secured by a first priority lien on substantially all of the Company’s assets. As of September 30, 2018 the Company had no borrowings under our Revolving Credit Facility.

Share Repurchase Program [Abstract]
Treasury Stock [Text Block]	Share Repurchase Program On October 26, 2017, the Company's board of directors approved a share repurchase program under which it authorized the Company, at its discretion, to repurchase up to $30.0 million of its common stock through December 31, 2019. Repurchases of the Company's outstanding common stock will be made in accordance with applicable laws and may be made at management's discretion from time to time in the open market, through privately negotiated transactions or otherwise, including pursuant to Rule 10b5-1 trading plans. There is no guarantee as to the exact number of shares to be repurchased by the Company. The timing and extent of repurchases will depend upon several factors, including market and business conditions, regulatory requirements and other corporate considerations, and repurchases may be discontinued at any time. We did not repurchase any shares of common stock during the thirteen weeks ended September 30, 2018 . We repurchased approximately 65,000 shares of common stock during the thirty-nine weeks ended September 30, 2018 for $1.6 million . As of September 30, 2018 , we have $28.4 million remaining to be repurchased under this plan.

Impairment of Long-lived Assets [Abstract]
Asset Impairment Charges [Text Block]	Impairment of Long-lived Assets The Company reviews long-lived assets, such as property and equipment and intangibles, subject to amortization, for impairment when events or circumstances indicate the carrying value of the assets may not be recoverable. In determining the recoverability of the asset value, an analysis is performed at the individual restaurant level and primarily includes an assessment of historical undiscounted cash flows and other relevant factors and circumstances. The Company evaluates future cash flow projections in conjunction with qualitative factors and future operating plans and regularly reviews any restaurants with a deficient level of cash flows for the previous 24 months to determine if impairment testing is necessary. Recoverability of assets to be held and used is measured by a comparison of the carrying value of the restaurant to its estimated future undiscounted cash flows. If the estimated undiscounted future cash flows are less than the carrying value, we determine if there is an impairment loss by comparing the carrying value of the restaurant to its estimated fair value. Based on this analysis, if the carrying value of the restaurant exceeds its estimated fair value, an impairment charge is recognized by the amount by which the carrying value exceeds the fair value. We make assumptions to estimate future cash flows and asset fair values. The estimated fair value is generally determined using the depreciated replacement cost method and discounted cash flow projections. Estimated future cash flows are highly subjective assumptions based on Company’s projections and understanding of our business, historical operating results, and trends in sales and restaurant level operating costs. As a result of above mentioned review process, during the third quarter of 2018 the Company identified six restaurants as impaired and recognized a $12.3 million non-cash loss on asset impairment during the third quarter of 2018. The Company did not recognize an impairment charge during the fiscal year 2017. The Company’s impairment assessment process requires the use of estimates and assumptions regarding future cash flows and operating outcomes, which are based upon a significant degree of management judgment. The estimates used in the impairment analysis represent a Level 3 fair value measurement. The Company continues to assess the performance of restaurants and monitors the need for future impairment. Changes in the economic environment, real estate markets, capital spending and overall operating performance could impact these estimates and underlying assumptions and result in future impairment charges.
