It seems impossible, but Subway has surpassed McDonald's as the world's largest restaurant chain. According to the Wall Street Journal, Subway now has 33,749 restaurants globally, while McDonald's has 32,737.
The number of Subway locations in the United States actually surpassed McDonald's nine years ago. Outside the U.S., Subway is also rapidly expanding and is planning to have more foreign stores than domestic ones by 2020.
McDonald's beats out Subway still in terms of total food sales. McDonald's sells more food, and they're trying to sell you even more by making you think of the place as more than just a fast food restaurant.
In recent years, McDonald's has been pushing its healthier food options, as well as its McCafe line of coffee drinks and free WiFi.
