Poutine was high on our list of things to try in Montreal. Cafe Poutine was a clear stop given it's name and location in touristy, Old Montreal location. The restaurant was small and crowded...it was tough trying to get between the tables.
The menu was promising - tons of Poutine options as well as sandwiches with a side of poutine as an option. My fiance had the poutine with smoked meat and I had the chicken, apple and brie sandwich- no poutine (I figured I could share). The portions were huge - I had a pile of fries on my plate (even though I had asked for no fries). The poutine was okay, not as mind-blowing as fries with cheese and gravy promised to be. My sandwich was so delicious. The baguette was perfectly toasted and the brie and apples were a great compliment.
The service was hurried and not very accommodating. i asked for no cheese on the sandwich, which they said wasn't possible. They also missed the no fries request.
The prices were also high- 2 waters, smoked meat poutine and a chicken sandwich set us back 35 CA. It makes sense for the district, but not for the overall experience.
Bottom line - if you're in the area and don't want to dig for poutine, this would be an ok stop. If you're looking for and awesome poutine experience, keep on walking.
