Pizza is pretty universal these days. There was one pizza place near me in college owned by an Indian family; they also sold Indian food. They didn't appreciate it when we tried to order a chicken tikka pizza, though.

Another pizza place near where I used to work was run by an Irish guy, who then later sold it to a Chinese guy.

Oh, and my favorite pizza place near where I used to live was run by a Dominican guy.

I think that pizza place food is not really connected with Italians in the US any more; it's pretty much just become mainstream American. Though there is still a trend for them to have Italian names.
