According to this article Subway has become the world’s largest fast food chain overtaking even McDonald’s. The chain now has 33,749 outlets in 95 countries whereas rival McDonalds have 32,737 and Burger King just over 12,000. Britain alone now has 1,350 Subway outlets. I suppose people perceive a sub from Subway to be a more healthy option than a McDonald’s burger when in many cases the calorie content is quite similar. I am surprised by the rapid expansion of the chain, it seems that almost every town now has a Subway.
