This trip, Guy Fieri's diving into a meaty smorgasbord. In Nashville, a funky neighborhood joint is serving up loaded carne fries and a skyscraper burger, and in New Smyrna Beach, Fla., a rockin' chef is cooking up real deal gnocchi and Grandma's hands-on pizza recipe. Plus, a spot with an out-of-this-world atmosphere is going huge with monster pork chops and an Italian meat extravaganza.
