You'll find that most "ethnic" food here in America is nowhere near what you will get in it's originating country. Italian food, starting with the pasta here and going forward, is no comparison to what I had in several port visits there, (including Naples). I'm sure they would by highly disappointed in our version of their dishes. Biggest difference was Chinese food, although it was in Hong Kong, which is not "pure" Chinese, it was much different that here, and I think I had chicken chow mein and Gen Tso's chicken if I remember correctly, (damn that was in 2003!). Korean food too. I think the closest comparison was Greek food, namely the gyro.
