Guy Fieri checks out some classics from coast to coast: In Portland, Ore., a neighborhood restaurant serving up Southern-style biscuits with everything on them; in Fort Worth, Texas, a roadside joint putting some heat in their standards like green chili lamb stew and rib eye with chipotle; and in North Miami Beach, Fla., a shack in a state park making all kinds of smoked fish.

Guy Fieri checks out some places keeping the feel of the past alive: In Idaho, the local landmark brought back to life, where they're dishing up big plates; In Portland, the old-time lunch counter where folks love the grilled cheese and home made tomato soup; And in Miami, the family joint doing seafood the way their grandparents did back in Cuba.
