I had a great experience at the Black Eagle while I was visiting Toronto. I went on a Tuesday night and made some friends right away, striking up a conversation with some locals sitting at the bar and with the bartender as well.
There's a small area up front with the bar (full bar and draft beer), a small landing up the stairs, and then a "play area" in the back. By the time 11:00 rolled around, the back area was filled up with horny bears and leather dudes.
