If you’ve never heard of In-N-Out, you’re not alone. It’s strictly a West Coast thing (though more recently they expanded to Texas), where it has a cult-like following. The company is notorious for controlling every part of the cooking process, including grinding its own beef for its hamburgers and delivering them fresh to its restaurants. It serves a simple menu of burgers, fries, and shakes, and is known for its “double double” (a burger with two patties and two slices of cheese), “animal style” burgers and fries (cooked in mustard with onions), and its long secret menu.
