Your responses will be varied for sure as so many people vehemently hate a restaurant while other will LOVE it. DO some research after the suggestions, look at the menus on either Disney dining reservations or
http://www.allears.net/menu/menus.htm. Then make your decision based on what you all will enjoy the most from the menu choices and the responses from us all. WIth that said, after 6 years of a week of free dining and trying almost all the restaurants at Disney, here are our favorites (our being me, DH, DD 10 & DD 12)
Magic Kingdom-
Lunch-
Columbia House
Dinner- Leave park, ride monorail to Grand Floridian to
1900 Park Fare (they have cinderella, prince charming, and supporting cast plus a picture and all for the normal TS price. i.e. not a signature dining).
Epcot
Lunch-
Tangirine Cafe (Morrocco). Great food and they have hamburgers for the kids meal which they don't even have at USA.
Dinner-This is a hard one. So many choices!
Coral Reef (awesome food and the whole wall of the restaurant is an aquarium. If you book at 5:30, you will get to see the scuba divers in the tank. Also, check in about 10 minutes early and offer to wait for a window seat. They will accommodate!)
Hollywood Studios
Lunch-
Studio Catering Company--one of the biggest menus for CS
Dinner-
Sci Fi Diner-The greatest for ambiance and wonderful desserts. This restaurant is a mock drive-in but inside. You sit in cars as tables while you watch old B movie clips. WE love this one.
Animal Kingdom
Lunch- no suggestion--not a huge fan of the options
Dinner--my strong suggestion is to leave AK and head to another restaurant on property for a sit down meal. Most of the time the park closes at about 5 or 6 so doing this is very attainable. This is the time to leave as the animals are in and there is just not that much to do. The restaurants here just aren't anything to write home about! This opens up such options for your dining pleasure. I would have to say that if you are to do that, you will find one of the most popular places to eat in all of Disney is Ohanas at Polynesian. It is a beloved restaurant with incredible food, and even some entertainment for the kids. So my suggestion would be leave AK, catch the bus to Polynesian and eat dinner at
Ohanas
Hope this all helps! If you have any other questions, just ask. We have been to almost all of them.
