On this trip, Guy Fieri is covering all things smothered. First up, Guy chats with mole masters in Salt Lake City who are crankin' out 10 different kinds of their special sauce -- and the new one is nuts. Then, in Florida, a diner is dishing out down-home comfort food like biscuits and gravy, and a corner joint in Reno, Nev., is keeping their Basque traditions alive by servin' up sweetbreads in style.
