This trip, Guy Fieri's diving into a world of cultural cuisine. There are indigenous recipes, like fry bread and pozole, in Phoenix, Arizona, and authentic Argentine specialties in Boulder, Colorado. Plus, a kabob spot in Memphis, Tennessee, is marinating meats with Ethiopian flavor.

Guy Fieri's having smokin' Southern meats and more. First in Mobile, Ala., a family-run barbecue joint is putting out a bomb Boss Burger with a side of rib candy and a stellar smoked brisket sandwich. Then in Atlanta, Chef G. Garvin's Southern-American steakhouse is serving up a next-level lobster mac and cheese and a decadent donut bread pudding.
