Some of the places mentioned in this thread are just solid places to eat that shouldn't need to be secretly enjoyed (Yorkshire County Fish Shop for one, but there are a couple of others). Tony's, on the other hand... I realize it could have changed, or it could have just been a bad night, but my GF and I had the worst food I've ever been served at a restaurant there. Her chicken was literally inedible and everything was awful. I'll never go back.
Anyway, my answer would be the NLE Electric Umbrella. I always had a meal there at EPCOT -- admittedly more for nostalgia than anything else, since it basically hadn't changed since I was a child, but the chicken fingers weren't bad.
