Delgadillo's Snow Cap Drive-In was opened in 1953 by Juan Delgadillo, Angel's brother, and it still feels like a Route 66 prank with a lunch counter attached. The building was made from scrap lumber, and the humour is everywhere: signs, old cars, odd props, and the kind of deadpan menu jokes that belong on a long road trip.
Come for burgers, ice cream, or just the stop itself. It is touristy, but it is the right kind of touristy for Seligman.
