Overview: This trip, Guy discovers a slice of history all over the country. In Annapolis, Maryland, two Irish brothers servin' up food from their homeland with a twist, like Guinness fried oysters with homemade coleslaw. In Brooklyn, New York, the ages-old, family run sandwich joint crankin' out tons of fresh sammies, like the steak pizzaiola with homemade gravy. And in Charleston, South Carolina, a couple of fine dining chefs are turnin' out low country classics like crispy chicken legs and the smoked pork loin po boy.
