Opened 68 years ago in Los Angeles by Harry and Esther Snyder, this drive-thru hamburger stand has become a California institution, easily recognizable by the yellow arrow in its logo. With locations throughout the state, In-N-Out is known for no-nonsense hamburgers, such as the cheeseburger topped with lettuce, tomato, and an onion slice—but it does add a secret sauce that hasn’t changed one iota since 1948.
Go big with a Double-Double—with two beef patties and all the fixings—or do like the locals and order off the Not-So-Secret Menu, which includes the grilled cheese sandwich (also topped with lettuce, tomato, and onions) and the bunless “protein-style” burger. Order some fries, too, and wash it all down with an old-fashioned vanilla, strawberry, or chocolate milkshake. If you’re traveling with kids or want your own California souvenir, ask for a free paper hat.
