Richard and Maurice McDonald opened McDonald's Bar-B-Que in San Bernardino, California. It was a typical drive-in featuring a vast menu and carhops. In 1948, the McDonald brothers shut down the restaurant for three months for alterations. They remade it into a self-service restaurant featuring only a few menu items: Hamburgers and cheeseburgers, soda, milkshakes, coffee, potato chips, and pie, with the core staple being the 15 cent hamburger. | Richard and Maurice McDonald opened McDonald's Bar-B-Que in San Bernardino, California.
