Chemistry isn't a club. It is a private members organization that hosts play parties at various venues. The parties aren't every weekend, it is every few weeks. When they do throw parties on a weekend, they'll sometimes do them on both Friday and Saturday night. Their membership is vetted and you have to apply to be a member.

Chemistry lets in select single males on any night they throw a party. However, they are very selective and the amount of single men are limited. They let in single guys because the single women want single men and don't want to just play with couples. It is nothing how like the clubs become when they let in any single guy willing to pay.

Please refrain from spreading bad information. Chemistry is a great club that has worked hard to build a great reputation among many in the community.
