There is a really massive Erasmus party on March 21, 2012. The facebook link is here: https://www.facebook.com/events/128060017371192/
Normally, the entrance is 20 lira in advance and 25 lira at the door. BUT, for Couchsurfing it's 15 TL. This price includes 1 Local Drink so it's not even that expensive.
There are no tickets, so you have to say you are from Couchsurfing when you are entering the club.
There is also free entrance to BEAT nightclub afterhours which also includes 1 FREE Shot.
The Club is also XLARGE on Istiklal Street. The party starts at 10PM.
Check the Facebook Event for details.
