This trip, Guy's firin' up the smoker and divin' into seafood. In Baltimore, a barbecue food truck dishing out killer pulled pork and righteous ribs. In Islamorada, Fla., a seaside shack serving standout shrimp fritters and doctoring up Guy's own fresh catch. And nearby in Key Largo, a market and restaurant smokin' up fantastic fish dip and putting out their own savory seafood specialty.
