Diners, Drive-ins and Dives

This trip, Guy's got a line on some righteous sammies. In Austin, Texas, the gourmet sandwich shop slicin' up duck pastrami and a knuckle sandwich. In Las Vegas, the roast beef po boy done the Cajun way. And in St. Paul, Minnesota, the burger joint reborn after a tragedy, grillin' up a new series of stuffed burgers.
