This trip, Guy Fieri is hitting culinary hot spots in South Beach, Fla. First, a real-deal taqueria servin' up scratch-made tortillas and grasshopper tacos. Then, an authentic German joint cooking up standout sauerbraten and killer currywurst, where he's joined by chef friend Carl Ruiz. Plus, a poolside oasis dishin' out legit paella and homemade linguine.
