On this trip, old friends are whippin' up new flavors. First up, in New York City, Guy Fieri follows a Triple D alum to his new place to check out old-school pizza and a new level of lasagna. Then, in Potterville, Mich., a place known for gizzards is frying everything from burgers to breakfast sandwiches. Plus a Belgian bistro in Cincinnati is serving waffles every which way.
