I would tend to stick with buffets where everyone can get a variety -
Epcot - Biergarten. My kids loved the band and being able to get up and dance was a great break for them. Also we all really liked the food.
MK - CP. A must do on every trip for us. The Pooh characters are fun and the food is good.
AK - Tusker House. Again the variety of food is good.
DHS - "50's Cafe. There is enough visually to keep kids occupied and the food is really good.
Hope this helps some.
