McDonald's is no longer the world's largest fast-food chain. A Chinese company called Mixue Bingcheng, which specializes in bubble tea and ice cream, has taken the top spot with over 45,000 locations worldwide. Most of their stores are in China, but they’re expanding across Asia and might even come to the U.S. someday. Their secret? Super low prices and a strong franchise model. Even though they have more stores, their revenue is still behind big names like Starbucks.
