McDonald's Corporation is the world's largest chain of hamburger fast food restaurants, serving nearly 47 million customers daily. At one time it was the largest global restaurant chain, but it has since been surpassed by multi-brand operator Yum! Brands (KFC, Taco Bell and others) and sandwich chain Subway.
