The problem with some of the restaurants in WDW are they are hit or miss. Sometimes you get a great meal, other times not so great. This happens a lot in the theme park restaurants but I find at the resorts the meals are fairly consistent (with exceptions of course.)
These restaurants are consistently good:
Chef Mickeys & Yacht Club Galley(now closed) for breakfast
Flying Fish Cafe at Boardwalk
California Grill at Contemporary
Grand Floridian Cafe (breakfast & dinner)
Kona Cafe at Polynesian (a personal fave!:slurp: )
Olivia's Cafe at Old Key West
Artist Point at Wilderness Lodge(best food on WDW property imo!:slurp: )
