I love this place! Their back patio is walled in all 4 sides by 4 storey brick buildings, which are covered by vines. There are trees and lots of seating. But get there early because on most nights it fills up quickly.
You are in the heart of Montreal, just of Ste Catherines but when you're on the "terrasse" at the Ste Elizabeth you feel transported to another world. They have lots of beers on tap (my favs are Boreal Blanche, Kilkenny and Rickards Red) and the service is great. I never got to the bottom of my pint before the waitress was over with an offer for another drinks.
This is my favourite place to drink in Montreal in the summer.
FYI they don't take debit. Only cash or credit.
