Accounting Policies [Abstract]
Basis of Presentation	1. BASIS OF PRESENTATION The accompanying unaudited consolidated financial statements include the accounts of BJ’s Restaurants, Inc. (referred to herein as the “Company,” “we,” “us” and “our”) and our wholly owned subsidiaries. The consolidated financial statements presented herein include all material adjustments (consisting of normal recurring adjustments) which are, in the opinion of management, necessary for a fair presentation of our financial condition, results of operations and cash flows for the period. Our consolidated financial statements and accompanying notes have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Certain information and footnote disclosures normally included in consolidated financial statements in accordance with U.S. GAAP have been omitted pursuant to the U.S. Securities and Exchange Commission (“SEC”) rules. The preparation of financial statements in conformity with U.S. GAAP requires us to make certain estimates and assumptions for the reporting periods covered by the financial statements. These estimates and assumptions affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of revenues and expenses. Actual amounts could differ from these estimates. A description of our accounting policies and other financial information is included in our audited consolidated financial statements filed with the SEC on Form 10-K for the year ended January 2, 2018. The disclosures included in our accompanying interim consolidated financial statements and footnotes should be read in conjunction with our consolidated financial statements and notes thereto included in the Annual Report on Form 10-K and our other reports filed from time to time with the Securities and Exchange Commission. Recently Issued Accounting Standards In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842). This guidance requires the recognition of most leases on the balance sheet to give investors, lenders, and other financial statement users a more comprehensive view of a company’s long-term financial obligations as well as the assets it owns versus leases. ASU 2016-02 will be effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. We will adopt ASU 2016-02 during the first quarter of fiscal 2019. Currently, all of our restaurant and our restaurant support center leases are accounted for as operating leases, and therefore are not recorded within our balance sheet. We expect this adoption will result in a material increase in the assets and liabilities on our consolidated balance sheets, but will likely have an insignificant impact on our consolidated statements of income or consolidated statements of cash flows. In preparation for the adoption of the guidance, we are implementing controls and key system changes to enable the preparation of financial information. Recently Adopted Accounting Standards In April 2016, the FASB issued ASU 2016-10, an amendment to ASU 2014-09, Revenue from Contracts with Customers (“Topic 606”). ASU 2014-09 provides a comprehensive new revenue recognition model that requires a company to recognize revenue to depict the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services and expands related disclosure requirements. ASU 2016-10 clarified ASU 2014-09 to address the potential for diversity in practice at the adoption. The standard also requires gift card breakage to be recognized as revenue in proportion to the pattern of gift card redemptions exercised by our customers. ASUs 2016-10 and 2014-09 were effective for annual and interim reporting periods beginning after December 15, 2017, and were permitted to be applied retrospectively to each prior period presented or retrospectively with the cumulative adjustment to opening retained earnings as of the date of adoption (modified retrospective approach). We adopted ASU 2016-10 on January 3, 2018, and elected the modified retrospective adoption method. As a result, we recorded a net cumulative adjustment of $4.6 million to opening retained earnings. We now allocate loyalty member transaction amounts between the goods delivered and the future goods that will be delivered, on a relative standalone selling price basis. For the thirty-nine weeks ended October 2, 2018, approximately $1.3 million of net revenues have been deferred until those loyalty points are redeemed in the future and approximately $1.1 million of gift card breakage has been recorded as revenues. Under the previous standard, we estimated the cost of the loyalty reward based on the equivalent cost of the food and beverage earned and recorded this cost as a marketing expense included in “Occupancy and operating” on our Consolidated Statements of Income. Additionally, under the previous standard we recorded gift card breakage as other income included within “Other (expense) income, net” on our Consolidated Statements of Income. ASU 2016-10 does not impact the calculation of our comparable restaurant sales or how we calculate gift card breakage.

Revenue Recognition

Revenue From Contract With Customer [Abstract]
Revenue Recognition	2. REVENUE RECOGNITION Our revenues are comprised of food and beverage sales at our restaurants. Revenues from restaurant sales are recognized when payment is tendered at the point of sale. Amounts paid with a credit card are recorded in accounts and other receivables until payment is collected. Gift card sales are recorded as a liability and recognized as revenues upon redemption in our restaurants. Estimated gift card breakage is recorded as revenue and recognized in proportion to our historical redemption pattern. The estimated gift card breakage is based on when the likelihood of redemption becomes remote, which has typically been 24 months after the original gift card issuance date. We offer a “BJ’s Premier Rewards” customer loyalty program, which enables participants to earn points for qualifying purchases that can be redeemed for goods in the future. We allocate the transaction price between the goods delivered and the future goods that will be delivered, on a relative standalone selling price basis, and defer the revenues allocated to the points until such points are redeemed. The liability related to our gift card and loyalty program, included in accrued expenses, on our Consolidated Balance Sheets is as follows (in thousands): October 2, 2018 January 2, 2018 Gift card liability $ 9,978 $ 14,955 Deferred loyalty revenue (post-adoption of ASU 2016-10) $ 10,510 $ — Estimated future loyalty costs (pre-adoption of ASU 2016-10) $ — $ 3,080 Revenue recognized on our Consolidated Statements of Income for the redemption of gift cards and loyalty rewards deferred at the beginning of each respective fiscal year is as follows (in thousands): For the Thirteen Weeks Ended For the Thirty-Nine Weeks Ended October 2, 2018 October 3, 2017 October 2, 2018 October 3, 2017 Revenue recognized from gift card liability $ 1,167 $ 695 $ 8,853 $ 6,812 (1) Revenue recognized from customer loyalty program $ 1,229 $ — $ 6,282 $ — (2) (1) Prior to the adoption of ASU 2016-10, gift card breakage was recorded as other income and included within “Other (expense) income, net” on our Consolidated Statements of Income and therefore not recognized as revenue. (2) Prior to the adoption of ASU 2016-10, loyalty rewards were recorded as marketing expense and included in “Occupancy and operating” on our Consolidated Statements of Income.

Long-Term Debt	3. LONG-TERM DEBT Line of Credit Our Credit Facility, which matures on November 18, 2021, provides us with revolving loan commitments totaling $250 million, of which $50 million may be used for the issuance of letters of credit. Availability under the Credit Facility is reduced by outstanding letters of credit, which are used to support our self-insurance programs. Our obligations under the Credit Facility are unsecured. As of October 2, 2018, there were borrowings of $95.0 million and letters of credit totaling approximately $14.5 million outstanding under the Credit Facility. Available borrowings under the Credit Facility were $140.5 million as of October 2, 2018. The Credit Facility bears interest at our choice of LIBOR plus a percentage not to exceed 1.75%, or at a rate ranging from Bank of America’s prime rate to 0.75% above Bank of America’s prime rate, based on our level of lease and debt obligations as compared to EBITDA plus lease expenses. The weighted average interest rate during the thirty-nine weeks ended October 2, 2018 was approximately 3.3%. The Credit Facility contains provisions requiring us to maintain compliance with certain covenants, including a Fixed Charge Coverage Ratio and a Lease Adjusted Leverage Ratio. At October 2, 2018, we were in compliance with these covenants. Interest expense and commitment fees under the Credit Facility for the thirty-nine weeks ended October 2, 2018 and October 3, 2017 were approximately $3.8 million and $3.2 million, respectively. We also capitalized approximately $0.1 million of interest expense related to new restaurant construction during both the thirty-nine weeks ended October 2, 2018 and October 3, 2017.

Earnings Per Share [Abstract]
Net Income Per Share	4. NET INCOME PER SHARE Basic net income per share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted net income per share reflects the potential dilution that could occur if in-the-money stock options issued by us to sell common stock at set prices were exercised and if restrictions on restricted stock units (“RSUs”) issued by us were to lapse (collectively, equity awards) using the treasury stock method. Performance-based RSUs are considered contingent shares; therefore, at each reporting date we determine the probable number of shares that will vest and we include these contingently issuable shares in our diluted net income calculation. Once theses performance-based RSUs vest, they are included in our basic net income per share calculation . The following table presents a reconciliation of basic and diluted net income per share, including the number of dilutive equity awards that were included in the dilutive net income per share computation (in thousands): For the Thirteen Weeks Ended For the Thirty-Nine Weeks Ended October 2, 2018 October 3, 2017 October 2, 2018 October 3, 2017 Numerator: Net income $ 8,516 $ 2,389 $ 40,125 $ 21,294 Denominator: Weighted-average shares outstanding – basic 21,118 21,354 20,861 21,620 Dilutive effect of equity awards 689 316 639 412 Weighted-average shares outstanding – diluted 21,807 21,670 21,500 22,032 For the thirteen weeks ended October 2, 2018, there were no anti-dilutive shares of common stock equivalents. For the thirteen weeks ended October 3, 2017, there were approximately 1.1 million shares of common stock equivalents that were excluded from the calculation of diluted net income per share because they are anti-dilutive. For the thirty-nine weeks ended October 2, 2018 and October 3, 2017, there were approximately 0.02 million and 0.5 million shares of common stock equivalents, respectively, that were excluded from the calculation of diluted net income per share because they are anti-dilutive.

Related Party	5. RELATED PARTY James Dal Pozzo, the Chairman of the Board of the Jacmar Companies (“Jacmar”), is a member of our Board of Directors. Jacmar, through its affiliation with Distribution Market Advantage (“DMA”), a consortium of large, regional food distributors located throughout the United States, is currently our largest distributor of food, beverage, paper products and supplies. In 2006, we began using DMA to deliver the majority of our food products to our restaurants. In July 2017, after conducting a market evaluation, we entered into a new five-year agreement with DMA. The new agreement expires in June 2022. Jacmar services our restaurants in California and Nevada, while other DMA distributors service our restaurants in all other states. Under the terms of our agreement with DMA, Jacmar is required to sell products to us at the same prices as the other DMA distributors. Jacmar does not provide us with any produce, liquor, wine or beer products, all of which are provided by other third party vendors and are included in “Cost of sales” on the Consolidated Statements of Income. The cost of food, beverage, paper products and supplies provided by Jacmar included within cost of sales and occupancy and operating expenses consisted of the following (in thousands): For the Thirteen Weeks Ended For the Thirty-Nine Weeks Ended October 2, 2018 October 3, 2017 October 2, 2018 October 3, 2017 Cost of sales: Third party suppliers $ 47,553 69.3 % $ 45,066 68.7 % $ 145,969 69.3 % $ 138,089 68.9 % Jacmar 21,047 30.7 20,487 31.3 64,628 30.7 62,376 31.1 Total cost of sales $ 68,600 100.0 % $ 65,553 100.0 % $ 210,597 100.0 % $ 200,465 100.0 % Occupancy and operating: Third party suppliers $ 58,709 96.1 % $ 52,913 95.8 % $ 170,350 95.9 % $ 157,186 95.8 % Jacmar 2,393 3.9 2,325 4.2 7,328 4.1 6,868 4.2 Total occupancy and operating $ 61,102 100.0 % $ 55,238 100.0 % $ 177,678 100.0 % $ 164,054 100.0 % The amounts included in trade payables related to Jacmar consisted of the following (in thousands): October 2, 2018 January 2, 2018 Third party suppliers $ 17,994 $ 18,738 Jacmar 3,866 6,537 Total accounts payable $ 21,860 $ 25,275

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Stock-Based Compensation	6. STOCK-BASED COMPENSATION Our current shareholder approved stock-based compensation plan is the 2005 Equity Incentive Plan (as amended from time to time, “the Plan”). Under the Plan, we may issue shares of our common stock to employees, officers, directors and consultants. We have granted incentive stock options, non-qualified stock options, and performance and time-based restricted stock units. Stock options and stock appreciation rights, if any, are charged against the Plan share reserve on the basis of one share for each share granted. Other types of grants, including RSUs, are currently charged against the Plan share reserve on the basis of 1.5 shares for each share granted. The Plan also contains other limits on the terms of incentive grants such as limits on the number that can be granted to an employee during any fiscal year. All options granted under the Plan expire within 10 years of their date of grant. Under the Plan, we issue non-qualified stock options as well as time-based and performance-based RSUs to vice presidents and above. We issue time-based RSUs and/or non-qualified stock options to other support employees. We also issue RSUs, and previously issued non-qualified stock options, in connection with the BJ’s Gold Standard Stock Ownership Program (the “GSSOP”). The GSSOP is a long-term equity incentive program for our restaurant general managers, executive kitchen managers, directors of operations and directors of kitchen operations. GSSOP grants are dependent on the length of each participant’s service with us and position. All GSSOP participants are required to remain in good standing during their vesting period. The Plan permits our Board of Directors to set the vesting terms and exercise period for awards at their discretion. Stock options and time-based RSUs vest ratably over three or five years for non-GSSOP participants and either cliff vest at five years or cliff vest at 33% on the third anniversary and 67% on the fifth anniversary for GSSOP participants. Performance-based RSUs generally cliff vest on the third anniversary of the grant date in an amount from 0% to 150% of the grant quantity, dependent on the level of performance target achievement. The following table presents the stock-based compensation recognized within our consolidated financial statements (in thousands): For the Thirteen Weeks Ended For the Thirty-Nine Weeks Ended October 2, 2018 October 3, 2017 October 2, 2018 October 3, 2017 Labor and benefits $ 577 $ 406 $ 1,699 $ 1,404 General and administrative $ 1,600 $ 1,335 $ 4,559 $ 3,867 Capitalized (1) $ 82 $ 75 $ 244 $ 218 (1) Capitalized stock-based compensation relates to our restaurant development personnel and is included in “Property and equipment, net” on the Consolidated Balance Sheets. Stock Options The fair value of each stock option was estimated on the grant date using the Black‑Scholes option-pricing model with the following weighted average assumptions: For the Thirty-Nine Weeks Ended October 2, 2018 October 3, 2017 Expected volatility 33.6 % 34.7 % Risk free interest rate 2.3 % 1.9 % Expected option life 5 years 5 years Dividend yield 1.5 % 0 % Fair value of options granted $ 10.77 $ 12.12 U.S. GAAP requires us to make certain assumptions and judgments regarding the grant date fair value. These judgments include expected volatility, risk free interest rate, expected option life, and dividend yield. These estimations and judgments are determined by us using assumptions that, in many cases, are outside of our control. The changes in these variables or trends, including stock price volatility, dividend yield and risk free interest rate, which may significantly impact the fair value of future grants, resulting in a significant impact to our financial results.

Income Tax Disclosure [Abstract]
Income Taxes	7 . INCOME TAXES We calculate our interim income tax provision in accordance with ASC Topic 270, “Interim Reporting” and ASC Topic 740, “Accounting for Income Taxes.” At the end of each interim period, we estimate the annual effective tax rate and apply that rate to our ordinary year to date earnings. The related tax expense or benefit is recognized in the interim period in which it occurs. The effect of changes in enacted tax laws, rates or tax status is recognized in the interim period in which the change is effective. The computation of the annual estimated effective tax rate at each interim period requires certain estimates and significant judgment including the expected operating income for the year, permanent and temporary differences as a result of differences between amounts measured and recognized in accordance with tax laws and financial accounting standards, and the likelihood of recovering deferred tax assets generated in the current fiscal year. The accounting estimates used to compute income tax expense may change as new events occur, additional information is obtained or the tax environment changes. On December 22, 2017, the Tax Cuts and Jobs Act (“TCJA”) was signed into law substantially amending the Internal Revenue Code of 1986. The TCJA made significant changes to the taxation of corporations such as the reduction of the highest corporate marginal tax rate from 35% to 21%, relevant tax law changes have been and will be incorporated into this and subsequent interim provision calculations. We have made provisional estimates of the impact of the TCJA and, as of the thirty-nine weeks ended October 2, 2018, our accounting for the tax effects of TCJA is incomplete. We will . As of October 2, 2018, we had unrecognized tax benefits of approximately $1.5 million, of which approximately $1.1 million, if reversed, would impact our effective tax rate. A reconciliation of the beginning and ending amount of unrecognized tax benefits is the following (in thousands): For the Thirty-Nine Weeks Ended October 2, 2018 October 3, 2017 Gross unrecognized tax benefits at beginning of year $ 1,516 $ 1,245 Increases for tax positions taken in prior years 8 — Decreases for tax positions taken in prior years (49 ) (3 ) Increases for tax positions taken in the current year 58 96 Lapse in statute of limitations (58 ) (64 ) Gross unrecognized tax benefits at end of year $ 1,475 $ 1,274 Our uncertain tax positions are related to tax years that remain subject to examination by tax agencies. As of October 2, 2018, the earliest tax year still subject to examination by the Internal Revenue Service is 2015. The earliest year still subject to examination by a significant state or local taxing jurisdiction is 2013.

Legal Proceedings	8. LEGAL PROCEEDINGS We are subject to lawsuits, administrative proceedings and demands that arise in the ordinary course of our business and which typically involve claims from customers, employees and others related to operational, employment, real estate and intellectual property issues common to the foodservice industry. A number of these claims may exist at any given time. We are self-insured for a portion of our general liability, our employee workers’ compensation and our employment practice requirements. We maintain coverage with a third party insurer to limit our total exposure. We believe that most of our customer claims will be covered by our general liability insurance, subject to coverage limits and the portion of such claims that are self-insured. Punitive damages awards and employee unfair practice claims, however, are not covered by our general liability insurance. To date, we have not been ordered to pay punitive damages with respect to any claims, but there can be no assurance that punitive damages will not be awarded with respect to any future claims. We could be affected by adverse publicity resulting from allegations in lawsuits, claims and proceedings, regardless of whether these allegations are valid or whether we are ultimately determined to be liable. We currently believe that the final disposition of these types of lawsuits, proceedings and claims will not have a material adverse effect on our financial position, results of operations or liquidity. It is possible, however, that our future results of operations for a particular quarter or fiscal year could be impacted by changes in circumstances relating to lawsuits, proceedings or claims.

SHAREHOLDERS’ EQUITY Stock Repurchases During the thirty-nine weeks ended October 2, 2018, we repurchased and retired approximately 0.2 million shares of our common stock at an average price of $42.31 per share for a total of $6.7 million, which is recorded as a reduction in common stock, with any excess charged to retained earnings. As of October 2, 2018, we have approximately $35.9 million remaining under the current $400 million share repurchase plan approved by our Board of Directors. Cash Dividends On July 23, 2018, our Board of Directors authorized and declared a quarterly cash dividend of $0.11 per share of common stock that was paid on August 27, 2018, to shareholders of record at the close of business on August 13, 2018. While we intend to pay quarterly cash dividends, any future decisions to pay, increase or decrease cash dividends will be reviewed quarterly and declared by the Board of Directors at its discretion.

Accounting Policies [Abstract]
Basis of Presentation	The accompanying unaudited consolidated financial statements include the accounts of BJ’s Restaurants, Inc. (referred to herein as the “Company,” “we,” “us” and “our”) and our wholly owned subsidiaries. The consolidated financial statements presented herein include all material adjustments (consisting of normal recurring adjustments) which are, in the opinion of management, necessary for a fair presentation of our financial condition, results of operations and cash flows for the period. Our consolidated financial statements and accompanying notes have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Certain information and footnote disclosures normally included in consolidated financial statements in accordance with U.S. GAAP have been omitted pursuant to the U.S. Securities and Exchange Commission (“SEC”) rules. The preparation of financial statements in conformity with U.S. GAAP requires us to make certain estimates and assumptions for the reporting periods covered by the financial statements. These estimates and assumptions affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of revenues and expenses. Actual amounts could differ from these estimates. A description of our accounting policies and other financial information is included in our audited consolidated financial statements filed with the SEC on Form 10-K for the year ended January 2, 2018. The disclosures included in our accompanying interim consolidated financial statements and footnotes should be read in conjunction with our consolidated financial statements and notes thereto included in the Annual Report on Form 10-K and our other reports filed from time to time with the Securities and Exchange Commission.
Recently Issued Accounting Standards	Recently Issued Accounting Standards In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842). This guidance requires the recognition of most leases on the balance sheet to give investors, lenders, and other financial statement users a more comprehensive view of a company’s long-term financial obligations as well as the assets it owns versus leases. ASU 2016-02 will be effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. We will adopt ASU 2016-02 during the first quarter of fiscal 2019. Currently, all of our restaurant and our restaurant support center leases are accounted for as operating leases, and therefore are not recorded within our balance sheet. We expect this adoption will result in a material increase in the assets and liabilities on our consolidated balance sheets, but will likely have an insignificant impact on our consolidated statements of income or consolidated statements of cash flows. In preparation for the adoption of the guidance, we are implementing controls and key system changes to enable the preparation of financial information.
Recently Adopted Accounting Standards	Recently Adopted Accounting Standards In April 2016, the FASB issued ASU 2016-10, an amendment to ASU 2014-09, Revenue from Contracts with Customers (“Topic 606”). ASU 2014-09 provides a comprehensive new revenue recognition model that requires a company to recognize revenue to depict the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services and expands related disclosure requirements. ASU 2016-10 clarified ASU 2014-09 to address the potential for diversity in practice at the adoption. The standard also requires gift card breakage to be recognized as revenue in proportion to the pattern of gift card redemptions exercised by our customers. ASUs 2016-10 and 2014-09 were effective for annual and interim reporting periods beginning after December 15, 2017, and were permitted to be applied retrospectively to each prior period presented or retrospectively with the cumulative adjustment to opening retained earnings as of the date of adoption (modified retrospective approach). We adopted ASU 2016-10 on January 3, 2018, and elected the modified retrospective adoption method. As a result, we recorded a net cumulative adjustment of $4.6 million to opening retained earnings. We now allocate loyalty member transaction amounts between the goods delivered and the future goods that will be delivered, on a relative standalone selling price basis. For the thirty-nine weeks ended October 2, 2018, approximately $1.3 million of net revenues have been deferred until those loyalty points are redeemed in the future and approximately $1.1 million of gift card breakage has been recorded as revenues. Under the previous standard, we estimated the cost of the loyalty reward based on the equivalent cost of the food and beverage earned and recorded this cost as a marketing expense included in “Occupancy and operating” on our Consolidated Statements of Income. Additionally, under the previous standard we recorded gift card breakage as other income included within “Other (expense) income, net” on our Consolidated Statements of Income. ASU 2016-10 does not impact the calculation of our comparable restaurant sales or how we calculate gift card breakage.
Net Income Per Share	Basic net income per share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted net income per share reflects the potential dilution that could occur if in-the-money stock options issued by us to sell common stock at set prices were exercised and if restrictions on restricted stock units (“RSUs”) issued by us were to lapse (collectively, equity awards) using the treasury stock method. Performance-based RSUs are considered contingent shares; therefore, at each reporting date we determine the probable number of shares that will vest and we include these contingently issuable shares in our diluted net income calculation. Once theses performance-based RSUs vest, they are included in our basic net income per share calculation .
