Authentic Chinese downtown Vancouver
Coal Harbour, and much of downtown and the West End, are touristy by nature.
But Hon's (acronym = House Of Noodles) on Robson near Broughton, is fairly down-home. Even has a small selection of dim sum (incl. vegetarian). But they are Cantonese through and through:
Other down-home restos, non-Cantonese, would be:
Next Noodle Bar
Shanghai Xiao Long Bao Restaurant
I used to like Dinesty. I still do but their dishes though good have a problem I see with many chinese restaurants - they are a bit one dimensional - meat or vegetable or tofu and add soy sauce. That bring said I love their tofu pudding with garlic sauce. The other dish to get would be the xlb (one of the best in Vancouver).
Ramen House (don't mind the japanese sounding name) is also quite good. It is near Macdonald and Broadway so not too far out of downtown. They also do a very good xlb.
