I had been reading about authentic Chinese places and how to spot one. This place meets the criteria: home made chili oil, black vinegar on the tables, Chinese patrons, cash only, and no water unless you ask. We had the pork and cabbage dumplings in soup and the pork, coriander, and shrimp dumplings fried. Both were really good, not doughy and very flavorful. The price was very good too. I already want to come back to Montreal all the way from Los Angeles just to eat here.
