Fair Value Disclosures [Abstract]
Fair Value Measurements	(4) Fair Value Measurements The carrying values of cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximate the fair values of these instruments due to their short-term nature. Cash equivalents consist of highly liquid investments of excess cash into U.S. Treasury bills, which have original maturities of three months or less. As of January 1, 2023, the Company had no cash equivalents. As of January 2, 2022, the Company recorded $75.0 million in cash equivalents, and classified these assets as Level 1 inputs, which are quoted prices (unadjusted) in active markets for identical assets that the Company can access at the measurement date. The Company records these cash equivalents monthly, based on the prevailing market interest rate as of the measurement date. Book overdrafts for checks outstanding are classified as current liabilities in the Company’s consolidated balance sheets. The carrying amount for borrowings, if any, under the Company’s credit facility approximates fair value because of the variable market interest rate charged to the Company for these borrowings. When the Company recognizes impairment on certain of its underperforming stores, the carrying values of these stores are reduced to their estimated fair values. The Company’s only significant assets or liabilities measured at fair value on a nonrecurring basis subsequent to their initial recognition were assets subject to long-lived asset impairment related to certain underperforming stores. The Company estimates the fair values of these long-lived assets based on the Company’s own judgments about the assumptions that market participants would use in pricing the asset and on observable real estate market data of underperforming stores’ specific comparable markets, when available. The Company classifies these fair value measurements as Level 3 inputs, which are unobservable inputs for which market data are not available and that are developed using the best information available about pricing assumptions used by market participants in accordance with ASC 820. As of January 1, 2023 and January 2, 2022, there were no long-lived assets subject to impairment.
