Your thought kind of ignores the common case when there may be two classes of food within one society. I once asked a friend to find out from his Japanese coworkers the best place in Tokyo to go to a fancy place for more high end versions of my favorites curry and gyudon. They were a bit baffled, the reason is that these are the "boring" baloney sandwiches everyone makes at home. It is not the focus of chefs who make fancy restaurants. Speaking of baloney, I was raised on fried baloney sandwiches on Scwables and have never seen those....must be cultural imperialism? Naw. It's not the most compelling example mainly just because US home recipes are dead simple and Pho seems less so. But home food and restaurant suited food are still different.
