Went here to pick up some micro-brews during our trip to Montreal for the Mondial de la bière. They have an entire little room dedicated to beer. Most of your usual beers are available as well as a pretty excellent selection of local Quebec brewed beers. I picked up a case of various Dieu Du Ciel beers as well as a few bottles of Unibroue that I typically don't see in the United States.
The main purpose of this store is a Cheese shop but they also have a great little selection of beer.
