The self-proclaimed “home of the original giant hamburger” has been serving up juicy burgers since 1952. But even though Nation’s has been in business for more than 50 years, the Northern California chain has changed with the times, now offering veggie burgers, wild salmon patties and lettuce-wrapped sandwiches for the carb conscious. Though it’s the made-to-order hamburgers—topped with your choice of chili, bacon, mild green chilies and standard veggies—that keep customers coming back, other favorites include creamy shakes and diner-style pies. The best part? The restaurant’s always open early till late, so you can enjoy the goodies whenever your stomach calls. Open 6 a.m.–1 a.m. Sun.–Thurs. and 6 a.m.–3 a.m. Fri.–Sat.
