The first McDonald’s was opened on May 15, 1940, by brothers Richard and Maurice McDonald. When it first opened, McDonald’s was a barbecue restaurant and in the early days, they had 25 items on their menu. However, at the end of World War II, the brothers realized that 80 percent of their sales were hamburgers. So they shut down the restaurant for a few weeks, and reopened with a smaller menu that had just nine items: hamburgers, cheeseburgers, three soft drink flavors available in 12-ounce cups, milk, coffee, potato chips, and pie. The idea behind the new store was to focus on speed and lower prices.
