It's all about the beef on this trip as Guy Fieri pops into a classic diner in Marietta, Georgia, for a taste of what's topping the charts these days. Next, it's on to San Antonio where a carwash-laundromat-kitchen combo is crankin' out killer burgers. And in Gilbert, Arizona, there's a joint pullin' all their ingredients from their own backyard and giving new meaning to the phrase, "farm to table."

Guy Fieri hits up his favorite Italian joints from over the years. In Scottsdale, Arizona, a real-deal Italian grocer crankin' out scratch-made staples like gnocchi and prosciutto that bring a tear to Guy's eye. And a San Antonio pizzeria serving authentic Neapolitan pie -- and they have the papers to prove it. Plus--BONUS! Guy pops into a by-the-slice stand in Austin, Texas, that the Nation has never seen before.

Guy Fieri goes to a Korean-taqueria mashing up unique flavors in their chicken tacos and bulgogi fries, a pizza joint putting out killer pastrami and outrageous scratch-made caramel rolls and serious strombolis.
