Old School Joints Diners, Drive-ins and Dives : Season 21 Episode 7

This trip, Guy's getting a taste of yesteryear. In Duluth, the Italian market/restaurant stacking up hearty homemade lasagna and a monster muffaletta. In Eugene, Ore., DDD's first all-vegan spot serving their signature tofu sammy and frozen peanut butter pie. And in Delta, Wis., the real deal retro diner dishing out righteous red-eye gravy and a surprising spin on the pancake.
