The link you are imagining between enjoying varied food and hierarchical racism is an insane leap to make so generally. You must see that. It seems that you think cities only exist to serve white people but as is the point, cities are often diverse, which is why they can support restaurants that serve different cuisines.

This isn't a very productive discussion, we could both be imagining entirely different cities and situations. I live in Australia, so I can't speak for American cities. The diversity in cuisine here comes from our now decades of immigration policies, people tend to immigrate for study or work, both of those things concentrate in cities, voila you have massive mixed communities serving mixed cuisines to that now multi-generational mixed community.
