This trip, Guy's taste buds are goin' South. In San Francisco, a local dive takes a New Orleans staple to a whole new level with their tiger prawn po' boy. In Bradenton, Fla., an authentic Cuban diner bringing authentic favorites to a small town, like real deal picadillo and boliche. And in Denver, a neighborhood favorite is crankin' out gumbo and breathing new life into classic gingerbread.
