This trip, Guy Fieri's celebrating homeland favorites from all kinds of diverse cultures. In Richfield, Minn., the Mexican restaurant-market combo dishing out real-deal tacos al pastor and carnitas tamales. In Denver, the Greek joint cooking up lights-out lamb ribs and a unique dessert specialty. And in Atlanta, the Southern spot serving up their spin on shrimp and grits, plus legit biscuits and gravy.
