Compensation Related Costs [Abstract]
Deferred Compensation	Deferred Compensation The First Watch Deferred Compensation Plan was adopted by the Company effective January 1, 2025. The First Watch Deferred Compensation Plan allows officers and other key employees to defer their compensation within designated annual limits. Discretionary matching and other credits may be made to the accounts of active participants, which vest based on an employee’s years of service or vest in full upon an active participant’s death, disability or a Company change in control event, as defined in the plan. Participants’ earnings on contributions fluctuate with the actual earnings and losses of available investment choices selected by the participants. While the First Watch Deferred Compensation Plan is unsecured, Management has elected to fund certain of these obligations through a rabbi trust, the assets of which consist of Company-owned life insurance policies. The assets held in the rabbi trust are not available for general corporate purposes and are subject to creditor claims in the event of insolvency. The cash surrender value of the life insurance policies held in the rabbi trust is recorded in other long-term assets. As of September 28, 2025, rabbi trust assets totaled $1.4 million. Changes to the cash surrender value and any increases or decreases to deferred compensation liabilities incurred under the First Watch Deferred Compensation Plan are recorded as general and administrative expenses. As of September 28, 2025, the deferred compensation obligation included in other long-term liabilities totaled $1.5 million.
