Hmmm... if money is no object, I'd say my fave is probably the Coral Reef at Epcot... but it's definitely on the pricy side of things.
We really liked Boma (at the Animal Kingdom Lodge) when we were down there last month... it's kind of a buffet... African Inspired dishes, but there was lots even for a picky eater like me

; And the price wasn't too bad.
We also liked Hollywood & Vine at Disney-MGM (we ate there on the Fantasmic dinner package... dinner and 'priority seating' for Fantasmic... you're brought in through the back-stage area)... again, a buffet... 50s themed... busy, but good food.
The food was good at the Luau, but it's not cheap, it's pay at time of reservation, and it fills up fast.
The Concourse Steakhouse at the Contemporary is pretty good for, well, steakhouse-type food... and we really enjoyed our lunch at the Rose & Crown at Epcot.
And for sandwiches and such, we REALLY liked the Earl of Sandwich at Downtown Disney
