Comparing menus at common fast food restaurants that are in both the US and UK (like McDonalds, Subway etc.) it seems the UK consistently has a larger number of vegetarian options or healthier meat (chicken/fish instead of beef/pork) options than the US. Given the diversity of the US population, especially in big cities like NYC and LA, I find it really surprising. The US certainly has more money so why not introduce more veg-friendly options on top of the usual hamburgers and hot dogs? Why is the UK "ahead" in this regard?
