There is a new BDSM/kink club in Philadelphia, SNS Dungeon. (SNS stands for “Saints and Sinners”, the old name of the venue.)
In order to attend events there, you must first become a member. This is due to the adult nature of the club.
For opening night, Mistress Zeneca is prioritizing people who are on her mailing list. To get on it, go to ElegantlyKinky.com.
If you want to join the club, go to SNSDungeon.com.
There are two types of membership, basic and premium. Premium allows you to interact with other members on the site through chat, private messages, etc.
Cost of membership and tickets are on the site.
