I'm working on a Cold War pulp thriller-type of story, and one of the key characters is a gay government employee. I'm looking to put a scene in a bar sometime between 1950 and 1965 (even if it was only open for a year or two in there), and ideally this bar would be a gay bar, or at least a bar known to be frequented by "confirmed bachelors". Anywhere in the DC metropolitan area (such as it was 50-60 years ago) is peachy keen. Did such a bar even exist? Names are super-duper, generic locations are even better.
Any information on what the place would look like, what he'd have to do to get inside (I'm assuming they wouldn't just let every cop in DC stumble in--there would be a password or doorman or secret entrance or...?), the etiquette of the club (who can touch who where, whether or not you'd dance on the bar, what sorts of drinks you'd be able to order without getting laughed out of the joint, etc.), and what hours the place would be open would be a huge bonus.
