The only Gay club in Santiago is Antifas Club. I can't remember the address but I will do my best to find it and e-mail it to you.
FYI: There is a chat room on the undernet #gaydomincanos. From the chat room you will able to get firsthand information and any party or event happening in The Island - concerning the Gay & Lesbian Community.
To get to the undernet you will need to download mIRC.
