Peridot is one of those weird animals that sells itself as a fancy dining lounge by day and evening, but wants to be a late night party spot for the trendy Yonge and Bloor crowd. I would say it only succeeds in doing the latter.
I've partied here many nights; Halloween, work parties, social gatherings. And I have to say I've never had a bad time. There is tons of space; a uncovered patio outside, a dance floor and bar upstairs, a bar and lounge area downstairs more lounge seating near the front of the bar. It has that dark, classy ambiance and drink prices to match. You won't get any drink specials here but the crowd is fun and young and the music is always great.
I would recommend this for anyone who wants to get away from the Richmond Street club scene and find a more sophisticated place to party!
