This is the place we are 100% sure to go for at least one lunch while in Montreal. As others have said, their dumplings are absolutely amazing. While we've stuck to the boiled ones - we never get tired of them as they are incredibly high quality and soooo tasty - not to mention as fresh as can be (since they make them a few feet away from where you sit).
This time around we were in their new, larger location - which is a little nicer than their old. A little less cramped and easier to find a seat during busy lunch-time hours. Bottom line - if you like incredibly delicious, authentic dumplings, go here immediately!
