What is the function of the waitlist at Texas Roadhouse?

The function of the waitlist at Texas Roadhouse is primarily to track guests waiting for a table efficiently. This system is crucial for managing guest flow and ensuring that the seating process is organized and fair. By maintaining an accurate waitlist, hosts can provide an estimated wait time to guests, which enhances the dining experience by setting clear expectations. This ensures that the restaurant can serve guests in the order they arrived, while also optimizing table turnover and maintaining a smooth operation during busy periods.

The other options do not fully capture the purpose of the waitlist. For example, seating guests only by arrival would overlook the importance of tracking wait times or accommodating larger parties effectively. Similarly, using the waitlist solely for special events or to provide breaks for hosts does not align with its primary purpose of managing the overall dining experience for all guests.
