When I was in Europe, the closest thing I had to American food was the BBQ chicken I made for my sweetheart's parents. This included baked potatos, done up right there on the grill (stuffed with sour cream, chives and a dash of garlic).
Otherwise, I was in culinary heaven trying all the cool stuff the locals had to offer. I will say that I did have a Pizza while I was in Torree Del Greco, Italy and it was different than what Americans are used to.
On a side note, thier version of Coke is alright but the Pepsi tastes like ass...no matter though, I was after the Bulgarian beer like Kamonitsa and Zagorka, both traditionally based on Czech lagers and completely badass.
