So this place has a larger second location in Downtown Montreal:

The food is fresh, delicate, and has a high quality, homemade taste. I was at their Sherbrooke location for a birthday party (set menu for large group) and the owners took extreme care to make sure I didn't eat peanuts -- i have an allergy. Very attentive owners and great staff. Super nice barmaid.
Not fancy but not rundown either. The perfect place before a movie or after the museum for a cocktail and plate of perfect dumplings.
Thanks!
