On this trip, Guy Fieri is diving into all sorts of off-the-hook flavors. First up, in the Florida Keys, Guy and Hunter are hittin' up a local landmark that's new to DDD -- but their deconstructed ceviche is the talk of the town. In St. Paul, the stuffed burgers and spicy apps at a neighborhood hot spot called us back for a third time, and, in Philly, classic comfort food is made with unexpected ingredients.
