What are all the ethnic foods you've ever eaten?

There are some exotic foods we tend to take for granted exist. Almost every city for example has a Chinese restaurant, a Mexican restaurant, and maybe an Outback Steakhouse. But this isn't universal for some reason. Someone asked me if I wanted to go to an Egyptian restaurant and I was like "wait, they have restaurants?"

A question for all those who would say they consider themselves ethnically fluent. What are all the cultural categories of food you've had?
