This all-American diner provides the ultimate nostalgic 1950s experience. Opened in 1957, the red-and-white striped eatery offers curbside service, delivering customers crisp yet juicy cheeseburgers, curly fries, onion rings, and cherry-topped milkshakes straight to their front seats. Go on the right day, and you could also catch a vintage car show.
