On the West coast there is better Asian cuisine, since it is less Americanized, but these guys do it well.
I gave up trying to find “real” Asian food on travels in the US. I know it is out there but I can't stomach much of it.
OTOH, many Asian guests to Texas end up having me take them to Chinese buffets. Go figure!
The secret to "American cuisine" is abundance, especially when it comes to meat. We have high quality ingredients and we add protein. I like most Asian food whether eaten here or there, but having had enough of chicken heads and chicken feat and sodden, soggy, unidentifiable green things that were supposed to be vegetables in northeastern China, I'm a bit less into "authenticity" than you are. IMHO, we do to food what we do to words: we adopt the best from the rest of the world and perfect it. The French have been mispronouncing words and names for centuries (e.g. Versailles, Vincennes, Orleans, etc.) and it took Anglophones to straighten it out. Let's hear it for cultural appropriation!
