I've had lots of poutine in lots of places - Smoke's is about average. While their selection of ingredients is impressive, the "traditional" (i.e. plain) poutine cannot stand on its own and compete with Quebec-style poutine and its squeaky cheese curds.
Still a great place to hit after a night of serious clubbing. Certainly better than any poutine I could get in London, but not quite as good as Ottawa/Montreal offerings!
