If you're visiting Montreal, this place is a must go. If you live in Montreal, it is still a must go! The best poutine place in town. Whenever I have a craving for poutine, I come here. I don't bother trying other places anymore because I always end up saying: it's better at La banquise.
There are 2 pages of different kinds of poutine but my favorite is the "La mart" with bacon hot dogs and mushrooms. The small plate is a good portion and price is good. The only downside is the long line-up and it can get very very loud depending on the crowd. Also, they don't take credit cards but that's pretty much a lot of business that is super busy. Interac and cash only.
