I have been to both Labyrinth and Pendulum, as well as Club Decadence and Bowery Bliss.
It always depends on what night you go. Any given night can be good or bad. You have to take your chances. I haven't been to Labyrinth in a few years. I stopped going because I didn't like the enviroment. Any time a woman would walk across the room, there would be a trail of guys following her, hoping to get lucky. It may have gotten better in the interim.
I like Pendulum on their Leather & Lace nights and Club Decadence on their Group Play nights.
Here are some basics about going to a swingers club as a single guy.
1. Don't expect to play. When I first started going I probably played 1 or 2 times out of every 5 that I went. It happens. If you can't handle paying $100 and not getting to play, then bring a date or stick to escorts. You have to be able to enjoy yourself without expecting to get lucky. If you expect it, not only will you be disappointed, but you'll also give off a vibe that will put people off and make it a self fulfilling prophesy.
2. Invest the time. It's ok to go and not play. Be sociable. Make friends with the host/hostess and staff. If you become a regular, your odds of playing go way up.
3. Most of the clubs have regular theme nights with different crowds. Pick a party and be a regular at it. If you go Thursday, Friday and Saturday, you will be going to a different party each night. If you go 3 Fridays in a row, you will see some of the same faces and make some connections.
4. If you are ok in group settings, the group play events are a better bet for getting to play. The women who go to those are generally looking to play with several guys. You have better odds than at a swingers club where you are hoping to hook up with 1 person.
5. Don't touch without consent. I know this seems like it should go without saying, but sometimes you may see 4 guys playing with a woman and it seems like she's taking all comers. You don't know what she negotiated with them first. Always ask before getting too close.
6. Along those lines, don't interrupt people playing to ask to join in. Ask before, or after for a next time, but interrupting is definitely a bad idea.
