Podnah's Pit (Portland, Ore.) • Donnie Mac's Roadside Cuisine (Boise, Ida.) • Whale's Rib (Deerfield Beach, Fla.) Guy Fieri checks out joints doing one-of-a-kind favorites from coast to coast; In Portland, a BBQ place smoking trout and lamb ribs; In Deerfield Beach, Florida, a beach town pub doing a new twist on Oysters Rockefeller; And in Boise, Idaho, a tire store turned diner where they'll put just about anything on their mac and cheese.
