Diners, Drive-ins and Dives

Blue Marlin Fish House (North Miami Beach, Fla.) • Fred's Texas Cafe (Fort Worth, Tex.) • Pine State Biscuits (Portland, Ore.) Guy Fieri samples some classics from coast to coast: In Portland, a neighborhood restaurant servin' up Southern-style biscuits. In Fort Worth, a roadside joint putting some heat in their standards. And in North Miami Beach, a shack in a state park makin' all kinds of smoked fish.
