Availability is read from each restaurant own booking platform when you load this page or change the date or party size. Restaurants that book only through OpenTable are listed separately: OpenTable does not allow automated availability checks, so rather than guess we send you straight to their booking page. The times shown are real bookable slots — clicking one opens that restaurant booking page. Walk-in and phone-only restaurants are not listed, because there is nothing for us to check. A spot marked "could not check" means the platform did not answer, not that it is full. Cancellations appear constantly, so it is worth re-checking closer to the hour.
