clean and expensive, sure, clean, expensive and authentic--probably not.
chinese food rocks, and i frankly don't care whether it's 'authentic' or not. i think pf chang's is fine, and have enjoyed both shun lee in nyc and ming dynasty in houston. that said, my husband and i went to china last year just to eat--four different provinces, four different cuisines--and have had other china trips as well. in fact, i'm typing this from my hotel in hangzhou. (try the hyatt, it's lovely.)
i've had nothing in the us or canada--
nothing--that tastes like the food in china, with the possible exception of those dried fried string beans and some dim sum. i must confess i've not tried chinese food in europe, being all-too happy to enjoy the local cuisines when i'm there.
my husband, who has been traveling to china for over 20 years, says that with the exception of a few high-end cantonese restaurants, most regional chinese cuisine isn't available anywhere except in china. that said, we're both grateful that we have something to eat that's not mexican or italian!
to get back on topic, i'm with the pu tong hua speakers--i don't care so much about the bathroom if the food is good enough--much like in china itself
