I don't know how authentic the cuisine is, but in the United States there are many kinds of "ethnic food" that are widely enjoyed, and "Chinese food" is one of them. In my town of about 25,000 there are six Chinese restaurants.
I love Chinese restaurants... but I also love Thai, Mexican, Greek, Lebanese...
If people at work decided to go out for lunch, the conversation might go like this:
"So, what should we have? Italian?"
"Naah, had it yesterday. Greek?"
"The Acropolis is OK but it's pretty expensive."
"I like Chinese, is there a good Chinese place around here?"
"For Chinese, the Hunan Pagoda is pretty good, and their lunch buffet is a good deal."
"Oh, sure, I've been there. I like their Moo Goo Gai Pan. Let's do that one."
