I just didn't want the argument about the Americanity of a Caesar salad; it's a quintessential American dish, but Wikipedia would give you fodder to debate. I sort of puckishly thought I was up for that debate, and then thought better of it.

America is huge. There is American food, universal throughout the 50 states, but almost definitionally anything that's 3,000 miles successful is going to be popular outside of the US as well.
