@edgarblythe,
I have some problems with the term "ethnic food", because usually those dishes are "Americanised" in the USA, here in Germany even "regionalised".
(For instance, there's no "European cuisine" even not a "German dish".)
That said, I just dislike just a few dishes of most ethnic food. (Though I do like fish, I don't like sashimi.)
German ethnic food: I don't like some of the North and South German bratwursts, I really dislike
blue kraut (if it isn't red cabbage) and
eisbein (if it isn't a "haxe").
