The Little Depot Diner (Peabody, MA), Santa Cruz Diner (Santa Cruz, CA), Diner (Norman, OK)

Guy Fieri hits nothing but diners on this trip. In Santa Cruz, California, where east coast diner meets Vietnamese cooking for everything from Reubens to spring rolls; In Peabody, Massachusetts, an old lunch car turned diner where the locals pile in for home made favorites like Boston Baked Beans; And in Norman, Oklahoma, a beloved local landmark serving award winning chili on everything from fries to burgers and hot dogs.
