Contact the martini bar in melbourne, i think it's on collins street..

Average for a club, but would be awesome for underages, I went to a couple of afterparties full of 16 year olds there last year, everyone was underage and they were still serving alcohol.

I believe it's a reasonable price, has 2 levels and a smokers area, not overly big so you could potentially pack it out for a 16th.

DO CONTACT THEM!
