I thought the recent news that McDonald's is no longer the largest fast food chain on the planet by number of locations was more interesting. Dethroned by a China's Mixue bubble tea franchise.
By number of locations, the top 5 are: Mixue, McDonalds, Starbucks, Subway, KFC. By revenue (note sorting in that table seems to be sorting strings), the top 5 are: Starbucks, KFC, Burger King, McDonalds, Chick-Fil-A. I'm surprised to see Burger King ahead of McDonalds.
