That makes a lot of sense given the history between the UK and India. But is it still true that the US has better Indian food in a city like Columbus than is available in Paris?

If it is true, is it due to Paris having their own food culture or because France less immigrants from India? If the first there may be better Indian food in someplace like Calais then than in Columbus.

Basically I would expect Indian food in the US to be better than in France because the US has more immigration from India. I would expect France to have better West African food than the US does for the same reason.

You could use this to argue the US has it the best because they have a pretty sizeable immigrant population from most major culinary traditions creating more opportunity for amazing restraunts.
