The club is located in a basement under the central station. The club has the best sound system in Israel and one of the best worldwide. They offer varied line-ups every week, but Thursdays are the club's line-up so usually this is the best time to visit there. Anyway, I'll recommend to sending a private message to their Facebook page and checkup
As I mentioned, the sound in the club is amazing. You can find there, mostly, some really awesome techno line-ups. But there are also some trance and other genres. Sometimes they make LGBT parties for those that is relevant for them. As I said, it's better to check up what's goin' on there in advance. There are 2 floors in the club.
Thursdays are usually awesome nights. Come around midnight because the tickets prices get more expensive later (usually at 1:00).
