For Table Service: I've done Chef's de France on a couple trips, once for lunch and another time for dinner. Dinner was better than lunch, the lunch menu was very limited but it was one of the few places that had a walk up availability. Like someone else said its kind of loud, but I like the people watching through the big windows, and you get to meet Chef Remy. They bring him around on a food cart.
LeCeller is my favorite but its not easy to get a reservation there, I've never been able to have dinner there, only lunch. Teppan Edo is real good and my second choice to LeCeller, its much easier to get a reservation and the hibatchi grill dinners are consistently good. Mexico has a nice ambiance, but the food was only ok. Rose and crown is good if you like UK food, I'm a fish and chips guy. Speaking of Rose and Crown its my favorite place to drink in Epcot, gotta love the atmosphere and piano players, shout out to the "Hat Lady" haha.
I liked China but haven't been since they re-did it a year or two ago. I'm looking forward to Via Napoli and the new Mexican place, they sound great!
