Diners, Drive-Ins and Dives: 21x7

Old School Joints

This trip, Guy Fieri’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, where he’s joined by Jimmy John Liautaud and his family.
