Many of the restaurants do not take reservation for dining after 5:00 PM. Others will only take reservations as early as 24 hours in advance. In most cases, just stopping at the dining cart and making you reservation the day you plan to dine, works best. The ones that usually need advanced reservation are Emerils, Spiderman breakfast, Mythos, and Tchoup Chop.
