Nexus 94 - greatest rave ever, was held in then-abandoned wharehouses near the Lachine Canal with people doing bungee in the middle of the dancing area. WOW!
Metropolis when it was only a nightclub and I was underaged and the whole lighting ceiling equipments could go up and down during songs and end up about 5 inches from your head.
The Dome BEFORE it was taken over by the portugese (when they was a naked chick & guy dancing from the top floor and when there was a swing on top of the dance floor).
Sona from the opening until about 2000. (I have great, great memories of Cream 97 at the Olympic Stadium with fire jugglers and Carl Cox and of Celebration when it was held at Sona - must have been 1998?).
I still have to find the right place now that all those are gone/have changed. Aria sucks (I've spent $125 to spend last NYE' there with Deep Dish and it wasn't cool AT ALL). The only solutions I found : go to Space, Pacha and Il Divino in Ibiza.
Ahh, Sona, those were the days...
