We stopped here twice during a week-long stay in Montreal, once because we purposely sought it out and again because it was convenient to where we were. The only food we ever tried was the roasted rosemary nuts, which were super small but sort of a perfect energizer to keep us moving and only like $2.50 or something.
The beer line-up is superb, and well-worth seeking out for that alone. Incredible and diverse selection. This was a winter visit so I can't speak to the outside space, but the front half of the place is drenched in sunlight if you time it right and a great place to warm up with on a cold day.
The service was probably close to the slowest of all the places we visited in Montreal, but certainly friendly which was really all that mattered. We would have likely ordered food on our second visit, but could tell we would be there for quite a while trying to accomplish that so just decided to have our delicious beverages and keep on moving.
I would just keep in mind this is a relaxing, friendly place and as long as you're not in a big hurry, it's pretty wonderful.
