Crystal Palace, Akerhause (Norway in Epcot), and Liberty Tree Tavern are my top 3, because...
Crystal Palace: food - buffet style and it was actually tasty. Granted we went for breakfast, so the food was typical breakfast food, but with all the people there and it was fresh was a definite plus in our book! Also the character interaction was wonderful.
Akerhause: (sorry for the spelling if it's not correct). Again, we went for breakfast and they have a buffet for some stuff, but the food (typical breakfast food) was brought to the table "family style". Food was hot and tasty. Character interaction was wonderful too. (Princesses and Mary Poppins - was great!)
Liberty Tree Tavern: Food was family style and so much to eat and it was really tasty. Character interaction was great too.
We had no kids - just 3 adults and we had the best time at the above three. In our opinions the DDP was the best at these three. Where else can you go and have fun, eat, and all you do is just sign a slip and off you go?

We did have the best waitstaff so we did end up leaving an "extra" tip but it was well worth it!
just my 2 cents!
