Anchor Bar (Superior, WI), Gatsby's Diner (Sacramento, CA), The Pit Stop (Merrick, NY)

This trip Guy's checking out the unexpected. In Merrick, New York, Italian family recipes -- in an old fast food joint. In Sacramento, California, a former Japanese grill turned diner where they're doing vegetarian beet sliders along with European classics like old school Rouladen. And in Superior, Wisconsin, a bunch of Triple D fans take us to their favorite burger place, that even they call a dive.
