I know this is a chain. But it's a very very good chain. They have great burgers (on delicious bread). Great beer. Great service. And AMAZING exotic poutine (not just your regular - although they have that too). The gravy might not be the best of all the plain poutine options in Montreal, but the special ones are truly special. Try the Frite Alors! Poutine (they're own special one) - you will not regret it.
This particular restaurant in the chain seems small compared to others.. just, fyi if you need a lot of space. I thought it was intimate and nice, though.
