Different choices for me. I have more than 2 favs but I would pick Tokyo Dining for dinner (view of Illuminations from corner window is awesome! (Food is good too) and Tutto Italia for lunch (though I would prefer dinner since I don't like to eat a heavy meal during the heat of the day.)
Tokyo Dining food
Chocolate Ginger Cake
Ginza combo
Tutto Italia
Copetta Sotto Bosco dessert
I forget what this was, not on menu any longer
Tagliata di Manzo
Farfalle (similar to fettucini alfredo which DD wanted)
Coral Reef for lunch, Tokyo Dining for dinner. I know everyone's been down on Coral Reef lately, but we really enjoyed our lunch there, and Tokyo Dining had absolutely amazing tempura and sushi. The chocolate ginger cake is also delicious.
