Not exactly a "goth" event, but many of us go. The music is alternative 80s and 90s. The venue is themed as a tiki bar. They also have an in-house smoke house so you can get some good barbecue. Always on a Saturday except in December when it's on the eve of the new year. Get there early for better (or any) parking.
Venue opens at 5PM but the actual event starts around 22:00 (10:00 PM) and goes until 02:00.
