I've already posted a few wordy comments, so... I've run out of serious analysis for now. Instead, I'll just briefly share my own experience of finding a Chinese restaurant in an unexpected place because... heck, why not.
Well, I was somewhere between Laramie, Wyoming and Denver, Colorado on a family trip several years ago, when hunger drove us to the only restaurant on the side of the road: a Chinese restaurant. It had some sort of very typical name like "China Palace" or "Peking Garden" and the interior looked like a normal, but plain, American cafe / small family restaurant, except with a few bright red Chinese trinkets here and there. There were only about 20 seats total in the tiny restaurant, and we were the only patrons there. The waitress looked at least half Asian, but greeted us loudly in English (and maybe with a hint of a Southern accent). She struck up a conversation with us, which I wish I could remember, because I'm sure my mom asked about stuff like the local Asian population and the waitress's background. I think the waitress could speak Cantonese. Anyway, what I DO remember, though, was that the waitress was pretty proud of her Spanish abilities, which she soon put to good use when a couple of Spanish-speaking patrons came in. My mom asked her about it and her response was something like "Well, yeah, a lot of our customers speak it so of course I do too!"
Also: that tiny little Chinese restaurant in the middle of nowhere had some of the BEST (I won't say "authentic") Mongolian beef I'd ever had. We had to order an extra takeout box of it for the road.
