There is a very good one located in the play areas in Atlantis and that gets used quite often
May I dare point out that a glory hole in a club or other semi-private setting is a sanitised version that provides a safe environment for the curious to experiment... in a location where a lot of sexually adventurous women are already present. In such a setting it is more fantasy/role play than it is reality.
I used to be curious about glory holes as a gay/bi male pursuit, because the concept of it was so alien. Personally I don't think I would ever want to use a toilet glory hole unless I was into a self-destructive~low self-esteem~humiliation spiral. I think as far as anonymous cursory sex with men goes, a straight woman can easily have as much as she may wish for, even going through daily life. Though to speak historically, as a closeted bisexual married, if there was a place where I could walk in, grope/finger a member of my own sex, walk out, I would go check it out
