Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation — The accompanying condensed consolidated financial statements are unaudited and have been prepared in conformity with generally accepted accounting principles in the United States of America (“GAAP”) for interim financial statements. The condensed consolidated financial statements were prepared on the same basis as the audited consolidated financial statements and, in the opinion of management, reflect all adjustments, consisting of normal recurring adjustments, necessary to present fairly the Company’s financial position, results of operations and cash flows for the periods presented. The condensed consolidated financial statements include the accounts of the Company and all subsidiaries required to be consolidated. All intercompany balances and transactions have been eliminated in the condensed consolidated financial statements. The condensed consolidated balance sheet as of December 25, 2020, has been derived from the audited consolidated financial statements of the Company. The accompanying condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and related notes for the fiscal year ended December 25, 2020, appearing in the Company’s final Prospectus filed with the SEC on July 29, 2021, pursuant to Rule 424(b) under the Securities Act of 1933, as amended (“Prospectus”).
Fiscal Period	The Company’s fiscal year is the 52 or 53-week period that ends on the last Friday of December. Fiscal year 2021 is a 53-week period and fiscal year 2020 was a 52-week period. The three months ended September 24, 2021, and September 25, 2020, were 13-week periods, and the nine months ended September 24, 2021, and September 25, 2020, were 39-week periods.
Tax Receivable Agreement	Tax Receivable Agreement — On July 29, 2021, the Company executed a tax receivable agreement (“TRA”) with certain pre-IPO owners (“TRA Participants”) that provides for payment by the Company to the TRA Participants of 85% of the amount of cash savings, if any, in U.S. federal, state and local income tax that the Company utilizes in the future from net operating losses and certain other tax benefits that arose prior to the IPO. The Company recognizes this contingent liability in its condensed consolidated financial statements when incurrence of the liability becomes probable and amounts are reasonably estimable. Subsequent changes to the measurement of the TRA liability are recognized in the statements of income as a component of other (expense) income, net.
Use of Accounting Estimates	Use of Accounting Estimates — The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported and disclosed in the condensed consolidated financial statements and accompanying notes. Accordingly, the actual amounts could differ from those estimates. If actual amounts differ from estimates, revisions are included in the condensed consolidated statements of operations in the period the actual amounts become known.
Recent Accounting Pronouncements Pending Adoption and Recently Adopted Accounting Pronouncements	Recent Accounting Pronouncements Pending Adoption — In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842), which establishes the principles to report transparent and economically neutral information about the assets and liabilities that arise from leases. This new guidance requires lessees to recognize the lease assets and lease liabilities that arise from leases in the statement of financial position and to disclose qualitative and quantitative information about lease transactions, such as information about variable lease payments and options to renew and terminate leases. Recently, the FASB issued ASU 2020-05, which deferred the effective date to fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. Adoption of the new standard is expected to result in the recognition of right-of-use assets and operating lease liabilities related to currently classified operating leases. The Company is still evaluating the materiality of the impact of this standard on its condensed consolidated financial statements and disclosures. In June 2016, the FASB issued ASU 2016-13, Financial Instruments — Credit Losses. The ASU sets forth a current expected credit loss (“CECL”) model which requires the Company to measure all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. This replaces the existing incurred loss model and is applicable to the measurement of credit losses on financial assets measured at amortized cost and applies to some off-balance sheet credit exposures. This ASU was effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption permitted. In November 2019, the FASB issued ASU 2019-10 which deferred the effective date to fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The Company is currently evaluating the impact this guidance will have on its condensed consolidated financial statements. In August 2018, the FASB issued ASU 2018-15, Intangibles — Goodwill and Other — Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract. The guidance aligns the requirements for capitalizing implementation costs incurred in a cloud computing arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. This standard is effective for annual reporting periods beginning after December 15, 2020, and interim periods within annual periods beginning after December 15, 2021. The Company is currently evaluating the impact this guidance will have on its condensed consolidated financial statements. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments in this ASU apply only to contracts, hedging relationships, and other transactions that reference London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued because of reference rate reform. This ASU is effective as of March 12, 2020 through December 31, 2022. An entity may adopt this ASU as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020. The Company is currently evaluating the impact this guidance will have on its condensed consolidated financial statements. Recently Adopted Accounting Pronouncements — In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. This update simplifies accounting for income taxes by eliminating some exceptions to the general approach in Accounting Standards Codification (“ASC”) 740, Income Taxes, related to intra-period tax allocation, the methodology for calculating income tax in an interim period and the recognition of deferred tax liabilities for outside basis differences. This update is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020, with early adoption permitted. The amendments in this update should be applied on either a retrospective basis, a modified retrospective basis, or prospectively, depending on the provision within the amendment. The Company adopted the standard for the fiscal year beginning December 26, 2020. Adoption of the standard did not have a material impact on the condensed consolidated financial statements.
