Not trying to steer you away from CR, never eat there. Heres places we like...at Magic Kingdom, Liberty Tree Tavern for dinner, Tonys Town Sq. lunch or dinner, and Crystal Palace if you like buffets.
At Epcot, hang on to that Le Cellier(cheese soup and pretzel bread,ahhhh) Nine Dragons(especially the Honey Sesame Chicken) San Angel is good but can be hit or miss(the atmosphere helps)and Biergarten is a good buffet.
At MGM, 50s PTC is good and fun, Mama Melrose is good, a bit hit or miss at times.
AK...well Flame Tree BBQ doesnt require an ADR but it does deserve honorable mention IMO.
At the resorts, Ohana is a definite for us. Whispering Canyon Cafe at WL is fun and can be very good, but has been hit or miss the last few times. ESPN Club, you cant get an ADR but it makes for a good meal if you find your self in the area and need to eat. Boma is also very good, though its not a must do for us.
We have never eaten at Artist Point but folks who have seem to really like it.
