Yes, I remember these places fondly and the good "fishing" that could sometimes be had. It was always advantageous to be able to see and converse in real time before sealing the deal, and to have a chance to gauge the "vibe" of those to choose from. Sadly, however, all that seems a thing of the past, not just in DC but practically everywhere. It's all on-line now, which has its own advantages, but I still miss "pressing the flesh" before you actually got down to "press the flesh."
DC also appears to have lost its previous scene of having numerous stripper bars to choose from for an evening's entertainment, and this, too, is sorely missed.
