Same goes for pretty much any major city on the globe, which is why I don't think you can name a best city in the world for food.
I have some rules of thumb about culinary tourism:
1) I'll research local demographics to see if there are any expat neighborhoods without a strong presence in my home city (NYC). For example, Marseilles has a decent amount of Comorans (i.e. from Comoros). Whereas a Comoran restaurant may not be listed online - at least, not in a language I understand - I'll ask the tourism bureau/do a search for Comoran neighborhoods, and hope that a Comoran place to eat exists.
2) You've also got the regional cuisines from a country. Tokyo might introduce you to an Okinawan or Hokkaido eatery, or a Kagoshima food fair; Shenzhen, China must be one of the greatest places in China to sample food from throughout that country.
3) The capital isn't always the best place for variety. I cite Dubai/Abu Dhabi as one example. But merely having an international presence doesn't guarantee quality all-around either.
