My wife and I live in Shanghai, and as a rule, every time we go to another city, we try out the "local Chinese" food at least once. This was our stops Montreal, and it was pretty damn legit dim sum. It's always a good sign when you go for dim sum and its full of old Chinese people large groups. Nothing in particular jumps out as being amazing, but in general the whole experience was very reminiscent of a real Hong Kong breakfast dim-sum experience.
