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 financial statements presented herein include all material 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 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 accordance 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, liabilities, 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 3, 2017. The disclosures included in our accompanying interim 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. Reclassifications As a result of the adoption of the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-17, Balance Sheet Classification of Deferred Taxes (Topic 740), reclassifications of financial statement amounts have been made to prior period to conform to the current period’s presentation. The adoption of this standard resulted in the reclassification of $18.4 million from current to long-term deferred taxes on January 3, 2017. Recently Issued Accounting Standards In February 2016, the 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. 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 are currently evaluating the impact that this guidance will have on our consolidated financial statements as well as the expected adoption method. 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 clarifies ASU 2014-09 to address the potential for diversity in practice at the adoption. ASUs 2016-10 and 2014-09 are effective for annual and interim reporting periods beginning after December 15, 2017, and early application is permitted. We are currently evaluating the impact that this guidance will have on our consolidated financial statements as well as the expected adoption method. The majority of the Company’s revenues are from food and beverage sales at our restaurants. ASU 2014-09 will not have an impact on revenue recognition related to food and beverage sales unless the sales are to a customer participating in our loyalty program. Currently, we measure our total loyalty rewards obligation based on the estimated number of customers who will earn and ultimately claim rewards under the program using the cost basis. Under this approach, we estimate the cost of a loyalty point based on the equivalent cost of the food and beverage earned by our customers. These expenses are accrued for and recorded as marketing expenses and are included in “Occupancy and operating” expenses on our Consolidated Statements of Income. Under ASU 2016-10, we will be required to allocate the transaction price between the goods delivered and the future goods that will be delivered, using the loyalty points earned, on a relative standalone selling price basis. The portion of the transaction price allocated to the future loyalty rewards will be deferred until the related loyalty rewards are redeemed. We will no longer record a marketing expense related to loyalty points earned. These new standards will not impact the way we account for gift card breakage. We are in the process of quantifying the impact of adopting these new standards as well as determining the adoption method.

Debt Disclosure [Abstract]
Long-Term Debt	2. 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 July 4, 2017, there were borrowings of $172.5 million and letters of credit totaling approximately $14.5 million outstanding under the Credit Facility. Available borrowings under the Credit Facility were $63.0 million as of July 4, 2017. 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 twenty-six weeks ended July 4, 2017 was approximately 2.1%. 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 July 4, 2017, we were in compliance with these covenants. Interest expense and commitment fees under the Credit Facility for the twenty-six weeks ended July 4, 2017 and June 28, 2016 was approximately $2.0 million and $0.8 million, respectively. We capitalized approximately $90,000 of interest expense related to new restaurant construction during the twenty-six weeks ended July 4, 2017, and June 28, 2016.

Earnings Per Share [Abstract]
Net Income Per Share	3. 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 issued by us were to lapse (collectively, equity awards) using the treasury stock method. Performance-based restricted stock units have been excluded from the diluted income per share computation because the performance-based criteria have not yet been met. 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 Twenty-Six Weeks Ended July 4, 2017 June 28, 2016 July 4, 2017 June 28, 2016 Numerator: Net income $ 9,639 $ 13,789 $ 18,905 $ 25,433 Denominator: Weighted-average shares outstanding – basic 21,573 24,146 21,752 24,212 Dilutive effect of equity awards 501 428 450 426 Weighted-average shares outstanding – diluted 22,074 24,574 22,202 24,638 For the thirteen weeks ended July 4, 2017 and June 28, 2016, there were approximately 0.5 million and 0.3 million shares of common stock equivalents, respectively, that were excluded from the calculation of diluted net income per share because they are anti-dilutive. For the twenty-six weeks ended July 4, 2017 and June 28, 2016, there were approximately 0.5 million and 0.3 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	4. RELATED PARTY The Jacmar Companies and their affiliates (collectively referred to herein as “Jacmar”) is one of our shareholders and James Dal Pozzo, the Chief Executive Officer of 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 supplier 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 Twenty-Six Weeks Ended July 4, 2017 June 28, 2016 July 4, 2017 June 28, 2016 Cost of sales: Third party suppliers $ 47,705 68.6 % $ 41,517 66.4 % $ 93,023 69.0 % $ 82,038 66.6 % Jacmar 21,812 31.4 21,052 33.6 41,889 31.0 41,171 33.4 Total cost of sales $ 69,517 100.0 % $ 62,569 100.0 % $ 134,912 100.0 % $ 123,209 100.0 % Occupancy and operating: Third party suppliers $ 52,562 95.8 % $ 47,896 95.5 % $ 104,273 95.8 % $ 94,843 95.6 % Jacmar 2,310 4.2 2,248 4.5 4,543 4.2 4,374 4.4 Total occupancy and operating $ 54,872 100.0 % $ 50,144 100.0 % $ 108,816 100.0 % $ 99,217 100.0 % The amounts included in trade payables related to Jacmar consisted of the following (in thousands): July 4, 2017 January 3, 2017 Third party suppliers $ 20,290 $ 25,363 Jacmar 6,247 5,782 Total accounts payable $ 26,537 $ 31,145

Stock-Based Compensation	6 Months Ended

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Stock-Based Compensation	5. 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 are charged against the Plan share reserve on the basis of one share for each share granted. Other types of grants, including restricted stock units (“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 stock options as well as time-based and performance-based RSUs to officers. We issue time-based RSUs and stock options to other support employees. We also issue RSUs and 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 mangers and restaurant field supervision. GSSOP grants are dependent on the length of each participant’s service with us and position. All GSSOP participants must remain in good standing during their service period. The Plan permits us to set the vesting terms and exercise period for awards at our 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 target achievement. The following table presents information related to stock-based compensation (in thousands): For the Thirteen Weeks Ended For the Twenty-Six Weeks Ended July 4, 2017 June 28, 2016 July 4, 2017 June 28, 2016 Labor and benefits $ 530 $ 505 $ 999 $ 908 General and administrative $ 1,363 $ 1,051 $ 2,531 $ 2,198 Capitalized (1) $ 78 $ 83 $ 143 $ 162 (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 grant issued was estimated on the date of grant using the Black‑Scholes option-pricing model with the following weighted average assumptions: For the Twenty-Six Weeks Ended July 4, 2017 June 28, 2016 Expected volatility 34.7 % 35.9 % Risk free interest rate 1.9 % 1.5 % Expected option life 5 years 5 years Dividend yield 0 % 0 % Fair value of options granted $ 12.13 $ 14.37 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 and risk free interest rate, may significantly impact the fair value of future grants, resulting in a significant impact to our financial results. The exercise price of our stock options under our stock-based compensation plan is required to equal or exceed the market close fair value of our shares on the option grant date or the most recent trading day when grants take place on market holidays. The following table represents stock option activity: Options Outstanding Options Exercisable Shares (in thousands) Weighted Average Exercise Price Shares (in thousands) Weighted Average Exercise Price Outstanding at January 3, 2017 1,227 $ 31.95 802 $ 27.73 Granted 163 36.28 Exercised (38 ) 27.08 Forfeited (6 ) 42.19 Outstanding at July 4, 2017 1,346 $ 32.56 871 $ 29.34 As of July 4, 2017, total unrecognized stock-based compensation expense related to non-vested stock options was $4.3 million, which is generally expected to be recognized over the next five years. Restricted Stock Units Time-Based Restricted Stock Units The following table represents time-based restricted stock unit activity: Shares (in thousands) Weighted Average Fair Value Outstanding at January 3, 2017 460 $ 39.75 Granted 131 37.63 Vested or released (52 ) 44.95 Forfeited (29 ) 39.76 Outstanding at July 4, 2017 510 $ 38.68 The fair value of our time-based RSUs is equal to the fair value of our common stock at market close on the date of grant or the most recent trading day when grants take place on market holidays. The fair value of each time-based RSU is expensed over the vesting period (e.g., three or five years). As of July 4, 2017, total unrecognized stock-based compensation expense related to non-vested RSUs was approximately $10.2 million, which is generally expected to be recognized over the next five years. Performance-Based Restricted Stock Units The following table represents performance-based restricted stock unit activity: Shares (in thousands) Weighted Average Fair Value Outstanding at January 3, 2017 54 $ 37.87 Granted 40 35.95 Vested or released — — Forfeited (24 ) 32.49 Outstanding at July 4, 2017 70 $ 38.68 The fair value of our performance-based RSUs is equal to the fair value of our common stock at market close on the date of grant or the most recent trading day when grants take place on market holidays. The fair value of each performance-based RSU is expensed for a quantity based on management’s current estimate of the level that the performance goal will be achieved. As of July 4, 2017, based on the target level of performance, the total unrecognized stock-based compensation expense related to non-vested performance-based RSUs was approximately $1.4 million, which is generally expected to be recognized over the next three years.

Income Tax Disclosure [Abstract]
Income Taxes	6. 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. In addition, 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. As of July 4, 2017, we recorded unrecognized tax benefits of approximately $1.3 million, of which approximately $1.0 million, if reversed would impact our effective tax rate. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in thousands): Balance at January 3, 2017 $ 1,245 Decrease for tax positions taken in prior years (1 ) Increase for tax positions taken in current year 65 Balance at July 4, 2017 $ 1,309 Our uncertain tax positions are related to tax years that remain subject to examination by tax agencies. As of July 4, 2017, the earliest tax year still subject to examination by the Internal Revenue Service is 2013. The earliest year still subject to examination by a significant state or local taxing jurisdiction is 2012.

Commitments And Contingencies Disclosure [Abstract]
Legal Proceedings	7. 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.

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 financial statements presented herein include all material 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 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 accordance 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, liabilities, 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 3, 2017. The disclosures included in our accompanying interim 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.
Reclassifications	Reclassifications As a result of the adoption of the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-17, Balance Sheet Classification of Deferred Taxes (Topic 740), reclassifications of financial statement amounts have been made to prior period to conform to the current period’s presentation. The adoption of this standard resulted in the reclassification of $18.4 million from current to long-term deferred taxes on January 3, 2017.
Recently Issued Accounting Standards	Recently Issued Accounting Standards In February 2016, the 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. 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 are currently evaluating the impact that this guidance will have on our consolidated financial statements as well as the expected adoption method. 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 clarifies ASU 2014-09 to address the potential for diversity in practice at the adoption. ASUs 2016-10 and 2014-09 are effective for annual and interim reporting periods beginning after December 15, 2017, and early application is permitted. We are currently evaluating the impact that this guidance will have on our consolidated financial statements as well as the expected adoption method. The majority of the Company’s revenues are from food and beverage sales at our restaurants. ASU 2014-09 will not have an impact on revenue recognition related to food and beverage sales unless the sales are to a customer participating in our loyalty program. Currently, we measure our total loyalty rewards obligation based on the estimated number of customers who will earn and ultimately claim rewards under the program using the cost basis. Under this approach, we estimate the cost of a loyalty point based on the equivalent cost of the food and beverage earned by our customers. These expenses are accrued for and recorded as marketing expenses and are included in “Occupancy and operating” expenses on our Consolidated Statements of Income. Under ASU 2016-10, we will be required to allocate the transaction price between the goods delivered and the future goods that will be delivered, using the loyalty points earned, on a relative standalone selling price basis. The portion of the transaction price allocated to the future loyalty rewards will be deferred until the related loyalty rewards are redeemed. We will no longer record a marketing expense related to loyalty points earned. These new standards will not impact the way we account for gift card breakage. We are in the process of quantifying the impact of adopting these new standards as well as determining the adoption method.
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 issued by us were to lapse (collectively, equity awards) using the treasury stock method. Performance-based restricted stock units have been excluded from the diluted income per share computation because the performance-based criteria have not yet been met.
