ON Club had its unexpected closing party on 4 January 2014. Management claims they are going to do some construction remodeling. In various Facebook postings, none of this was even slightly hinted upon. Strange that this happened at year end, when its lease could have been up for renewal. Many guys don't believe it will reopen or will go straight.
This event is listed inactive, below is the original description:
ON is Prague's largest gay night club. Open until at least 5am every day.
