The first McDonald's restaurant opened in San Bernardino, California, USA.
The first McDonald's restaurant was opened on May 15, 1940, by brothers Richard and Maurice McDonald in San Bernardino, California. It was a drive-in restaurant with a simple menu of hamburgers, fries, and drinks, and used an innovative "Speedee Service System" to ensure that orders were prepared quickly and efficiently. The restaurant was a huge success, and the brothers went on to open several more locations in California. The McDonald's franchise system was later developed by businessman Ray Kroc, who purchased the rights to the company from the McDonald brothers and oversaw its expansion into a global fast food giant.
