Bob's Clam Hut (Kittery, ME), Mama Cozza's (Anaheim, CA), Tune Inn Restaurant & Bar (Washington DC)

This trip Guy's pulling up for favorites the way they've always been done. In Kittery, Maine, a roadside shack serving the same fried clam recipe since 1956. In Washington, DC, a self-proclaimed dive that's been a go to burger spot on Capitol Hill since '47. And in Anaheim, California, a 45-year-old, third-generation, Italian joint doing sauces, pizzas and parmesans ... all from scratch.
