These are just my preferences. If you are going with or without kids, or if you have particular tastes in food (certain flavors, ethnic styles, etc. ) or setting (formal, informal, CS, TS, buffet, characters or no characters, etc.) you may not like the same ones I do. Check out menus for your best options.
1. Magic Kingdom Park
Breakfast- CS- Main Stree Bakery has some good treats. TS - Cinderella's Royal Table to see the inside of the Castle or Crystal Palace for the food

Lunch- CS- Pecos Bill's, Cosmic Ray's or Columbia Harbour House
TS- Plaza
Dinner- TS Crystal Palace OR take a monorail and hop to Kona- the best restaurant on property! (says me
