There is definitely something cool to be said about living in a place where one day I can eat some amazing Greek food and then the next day have Chinese or Mexican. The US has some amazing options on almost every street corner (in a city, get fucking rekt suburbia)

"western food" is something that only exists in foreign countries anyways, like "asian food". If it is something that is available, it's not really what I'm used to from home, but some weird mish-mash of what someone thinks the typical american/british/german/other (in that order) eats. And on top of that, it's usually terrible quality, not due to a lack of skill, just well, not having the right ingredients, not knowing the nuances of the food or what it's supposed to taste like. So between a postmodernist interpretation of what someone thinks I eat, or proper local food, I really don't understand why you'd ever not eat the local food.

But it's not only western people. Japanese/Taiwanese/Chinese traveling in Switzerland do like to buy/bring instant noodles and cook them at the hotel instead of eating local food (not that there really is local swiss food, there's like 3 dishes and then it's mostly an amalgam of italian, french and german cuisine). Part of that is the high price, but not only. And from the few times I traveled in other european contries with friends from those asian countries, it seems common enough that they prefer to eat at asian restaurants. Except for italy, where everyone loves the local food.
