Melbourne boasts an abundance of clubs and pubs and bars, so it's often difficult to find the good ones without having a couple of less than exciting nights. It looks like it's down a dingy alleyway where with a little bit of luck you won't be killed, and there's usually a group of drunken twenty-somethings trying to get inside but being rejected by the doorman.
If you make it inside alive, then you will find that there are three floors, all of which sport very similar music. Baggy-trousered ravers consume all three dance floors in a surge of energy and sweat. On the second floor there are couches if you find yourself too tired after hours of dancing like a lunatic.
3D is the place to go if you're up for a crazy night and have absolutely no concern for your safety, and so it is suitable for anyone who wishes to celebrate their 21st or 18th birthday party, although I can not be held responsible for any injuries or deaths.
