This buffet in the Walt Disney World Dolphin would be forgettable were it not for its hours -- Tubbi's serves up hot food around the clock. The menu includes sandwiches, pizza, and two daily blue-plate specials, like meat loaf or barbecued chicken. Also on hand are nonfood necessities like laundry detergent and disposable diapers: there if you need them at 3 AM. Breakfast, including a worthy omelet, is served from 6 to 11:30 AM.
