I would have suggested Lumiere or West but both restaurant's head chefs are leaving (not sure if they left already) I am not sure if they can retain their quality. If you are looking into fine dine (expect to dress at least smart casual for that), you can try tasting menu at C (regular menu isn't so good... IMO).
Fuel has pretty good food but it's less formal and the room isn't very romantically set. Haven't go fine dine for a while.. not sure any more
