California’s first drive-through hamburger stand was the brainchild of Harry Snyder, back in 1948. There are more than 150 In-N-Outs today, mostly on the West Coast), but it’s not a “chain” in the modern sense of the word. The company is still privately held and has never licensed a franchise. There are only three things on the menu: burgers, fries, and drinks (milkshakes being the highlight), and all of them are made on-site and all of them are delicious.
Don't miss: The house specialty “animal-style” burger, which comes with pickles, extra “spread” (the house condiment, a Thousand Island-esque caloric extravaganza), extra grilled onions, and mustard fried onto each meat patty.
