If I were at Epcot, Le Cellier has recently updated their menu. The atmosphere in there is low lighting, rustic aesthetics. Bistro De Paris I hear is the place for romance.
I liked the Plaza restaurant at MK. Limited seating made for a more intimate setting than Tony's. Romantic turn-of-the-century decor. Tony's is romantic just because of the "Lady & The Tramp" reference. I went with a couple of friends (who are now married) and got a pic of them doing the spaghetti kiss. HAHA!
