This trip, Guy Fieri's getting stuffed and sandwiched. In Los Angeles, a taco truck is going big with the birria and putting out tasty tostadas. In Bend, Ore., it's Polish-palooza with lights-out pierogis and a cabbage specialty. Then in Milford, Ohio, an elevated diner is spicing up their chicken sandwich and pairing short rib grilled cheese with kimchi tomato soup.
