Slammer is a large gay men's only cruise and play club, with darkroom and private cabins.
Slammer is a B.Y.O.B. BAR- bring your own bottle and your bar tender will fix you a cocktail. They will save your bottle so that every time you come in you can be served. Don't forget to tip the bar tender though.
You need to become member to enter, so bring your ID. The club is cash only.
