Fondue would be fun, a cheese one before your main course would mean your gf's pumpkin pie was not upstaged.....
Also, it occured to me that the best part of a romantic trip for me is the late breakfast next morning, have you planned that? Its much easier of course, get a good loaf on the way up, or pastries or muffins, or some pancakes and bacon (I love north American breakfasts :)) and lovely hot chocolate or coffee.
Chocolate is a reuring theme in romantic meals, its the endorphins that it is meant to release and its melting point.....invaluable!
In omnibus amor et iustum
