In my head, I think I counted around 11-12 places above 72nd on UWS that I know about. They're literally every few blocks and on some streets, 2 different places. That doesn't include the indies giving massages in the Lincoln Center area.... Or Columbus Circle area.
I appreciate the community here and sharing spots and what girls do and for how much and all that, but what is missing is good old fashioned chemistry, attraction, loyalty, etc. I would suggest to any monger that if they go to a place and are kind, clean and respectful, and continue to be a good customer multiple times and always tip well, that things WILL develop nicely. Obviously it helps to be young, fit and handsome -- none of which I am, by the way.
But I have made a habit around town and being a good ambassador and complimenting girls, be friendly, tipping well. It tends to open up interesting doors.
But if someone is just looking for a wham/bam, thank you kind of experience, then yes - the UWS is a barron wasteland of opportunity.
