There was a kind of place that used to be around that is difficult/impossible to find these days:
--Mid-range in price i.e. a good bit more than street action, quickie joints, or NJ dive bars, but less than the mainstream extras experience as described above, or most of the more expensive independents. It seems like the low end and high end have survived at the expense of the middle, in pricing terms.
--An incall with a good selection, with some variety and generally much better quality than the low-end options. Incall with a selection is just a different experience than outcall, just as a brothel is a different scene than a UG club.
--Fairly easy to find and get into, with standard prices. The sex business is a lot more paranoid than it used to be.
These places used to advertise in the back of the Voice, NY Press, and Screw...you could call up and get in if you sounded reasonable...you could ask who was working and there would be some options; you could call a few places until you found someone to your liking. While there was variation in quality, you pretty much got to do what you were expecting to do, and didn't have to know anyone to get in, or worry about being ripped off.
I guess Julie's was the last of this kind of place, but there used to be a lot of them; people still ask about them in the "Remember When?" threads here.
