We definitely have a lot of favorites, but the one restaurant we always make sure to book first is the Garden Grill. It is a very neat setting, characters stopping by throughout, you never run out of food as long as you are hungry. It is family-style dining so you don't get as many of the "menu options" but the variety is still plenty to satisfy our family.
A close second is T-Rex. I'm a sucker for some of those themed restaurants, and T-Rex has a good menu selection. Prices weren't as bad as I might have thought, either.
