In Epcot, our favorite is Le Cellier, but that's a very hard ADR to get and with the change to a Signature coming in March, I'm not sure what it'll be like. Currently, the filet mignon with mushroom risotto, chedder cheese soup, Le Cellier hamburger are all very good.
I also like Tutto Italia and Via Napoli (Via Napoli has the same lunch and dinner menu) for lunch. At Tutto the braised short ribs were excellent, as were all of the desserts. At Via Napoli, the calamari appetizer was very good. I had the proscuitto and melon pizza which I highly recommend.
I've had lunch at Rose & Crown and Les Chefs, but prefer both for dinner. However, at Les Chefs the onion soup, braised beef, and steaks are very good and are on both menus.
