This was one of the best finds while in Montreal. I was with some friend and we were going to watch hockey at the Bell Centre, but wanted to get a few beers before the game. BM looks like a chain restaurant from the outside, but the food is really good quality and service is top notch. I suggest sitting on the first level either at the bar or in the back by the grill.
We went twice in one day and the service was awesome both times. Get the charcuterie! I highly recommend the Serrano Ham, pate, and potted chicken liver mousse.
They have a tremendous selection of beer. It seems like you really can't go wrong! There's an awesome tripel for only $5 although I can't remember the name. It's 9% alcohol. Ask for it.
