On this trip, Guy Fieri's grabbing standout sandwiches and diving into some serious spice. In Longmont, Colo., a spot putting out a primo pork burger and going crazy with cauliflower. In Columbus, Ohio, a Chicago-style joint killin' it with Italian beef and real deal gyros. And Food Network's Aarti Sequeira and Jet Tila join Guy in Los Angeles, where a champion chef dishes out fiery Thai specialties that will get your taste buds hoppin'!
