I can’t figure out what’s “wrong” or “horrifying” about this menu.
There are exactly 2 things which are specifically Southern (as in the southeast region of the contiguous 48 states of the US), and those are the “hushpuppies” (bits of fried cornmeal dough) and the “cheerwine” (cherry soda from a small-scale soda manufacturer; think regional microbrew for beers but non-alcoholic).
Absolutely nothing else on this menu is even slightly dubious if you’re familiar with, oh, restaurants in America in general. Sure, there are a few things on the menu from the Southwest (quesadilla is mentioned twice, lol), and they call their milkshakes “fancy shake” (charging $1 extra for one of those), and their tea isn’t listed as hot or iced--though it’s probably iced and probably pre-sweetened, which for me would be awful--but I wouldn’t call those “horrific” either...
