Our absolute must do when we are at Disney is eat at Flippers Pizza (more than once if we can fit it in). They have some of the best pizza (and garlic bread sticks) we have ever had. We have been to the one in Old Towne Celebration and the Lake Buena Vista one right off Hotel Blvd past DTD. Our favorite is probably the Lake Buena Vista one solely because they have more space than the Old Town location. Food is always great at both.
