If I am doing a whirlwind tour of Toronto for someone out of town, this is normally my bar of choice.
It's petite, packed with ambiance, chatter, and dim lighting, and the friendliest bartenders that I can recall in Toronto.
My only issue is that it is a tad pricey. Maybe it's a built-in cover charge for the word-of-mouth reputation, or a tax for sitting in one of their ten chairs, or the fact that it is was on Ossington before it was Bourgeossington, but whatever! No one is annoying and I always get a kick out of walking past it when I take a friend there.
They do NOT take credit cards.
