This trip, Guy Fieri’s traveling the nation, digging into all kinds of killer grub. In St. Petersburg, Fla., a lights-out spot loadin’ up the righteous ramen. In Lansing, Mich., a funky joint frying up everything from wings to pig skins to chicken gizzards. Plus, a New Orleans smokehouse puttin’ out Big Easy favorites like sausage meat pies and spicy shrimp boudin.
