This trip, Guy Fieri's sampling sandwiches, sausage and even a little schnitzel. In Portland, Ore., a standout spot servin' up specialties straight out of Switzerland. In Charlotte, N.C., a funky food truck dishing out grilled cheese with all kinds of culinary twists. Plus, another Charlotte stop at a hot dog joint making sausage from scratch and a classic chili cheese Coney.
