Hackensack, New Jersey
This New Jersey landmark was dubbed "the Diner of the Future" when the original was unveiled, at the 1939 world's fair in Queens, New York; today the tiny restaurant, decked out in red, white, and silver, has lost none of its appeal. Customers sit at a sliver of a counter and watch the cooks assemble sliders (patties, strings of onion, and petite potato buns) right on the griddle. It's performance art at its most delicious.
