This trip, Guy Fieri's digging into a righteous mashup of flavors. In Orlando, Fla. Joey Fatone is riding shotgun to a potato-centric palace, plus a trip to his very own hot dog hangout. And in Palm Springs, Calif., a joint stackin' up short ribs for lunch and puttin' their spin on a classic breakfast pastry. Plus, a dynamite deli serving up real-deal latkes and turkey pastrami.
