Our favorites are:
MK - Nothing - does anyone really eat here? We only get a drink and pickle, if we're really hungry, take the monorail to the Grand Floridian Cafe!!!
AK - We've tried Tusker House - OK, but, again, we'd usually wait for a better place to eat outside the park, like one of the hotels.
MGM - We love going to Prime-Time-Cafe - Our spot is at the bar, and we like to order some shrimp cocktail with our wine and some chicken noodle soup. My husband likes the club sammy and my son LOVES the milkshakes!!!
Epcot - Our favorite dining place!!!! LeCellier for lunch (hubby loves the trout), and for dinner, either Le Cellier again or England, France or a bratwurst from Germany! (Honestly, we love to drink around the world, more than "eat" around the world!!!)
