Chosen for cheapness, relative to other restaurants on the street, and a vegetarian-friendly menu. It's on a super fun street of restaurants with outdoor eating areas, if you haven't been here.
The food was all good, we ended up up with more than we could eat, and the beer servings seemed very generous.
There is a line, but it wasn't too bad. We were seated at a long table that had another couple at the other end, and all had plenty of room for outdoor dining. It drizzled a bit at one point but the umbrellas were enough to keep the rain out.
The poutine was the only one I had while in Montreal, and I thought it was very good!
