Salons are not normal bars, but brothels in private apartments.
In general, you have to call them first, and you need to
speak Russian a little bit as they usually don't speak English. Then they will tell you a place to go to (which can be their actual address, but also, an intersection of 2 streets, a metro exit, or a shop/restaurant/massageplanete near their apartment). There, you must call them again. In the best case, they'll just tell you the apartment number and buzz you in. In the worse case, you'll have to wait for them to send somebody to meet you and guide you back to the apartment.
Once you know the place, you just go back there, call them saying that you are a returning customer and they'll buzz you in.
Each salon can have anything Reviewom 1-2 to 15-20 girls, basic to fancy theme rooms, Reviewom 2000 RUR an hour to 6000 RUR or more. There are tons in Moscow. To give you an idea, here are some which have a website:
Fantasys (
http://www.fantasys.nu)
There are on Stratnoy Bul., very near Night Flight. One hour was 3000 RUR (but prices change fast in Moscow)
Charme'l (
http://www.charmel.biz)
They are near Arbatskaya metro station
Elit (
http://www.elit.tv)
Salon 69 (
http://www.salon69.hwsite.ru)
They had a salon on Sadovaya-Kudrinskaya, but it's no longer on their website now and the site name has changed to Escort69, so maybe they changed business. Although they did have nice girls, the photos on the site now look fake. Don't know...
Erotic Massage (
http://www.erotic-massage.ru)
They have 2 locations, on Studenchevskaya and on Leninskiy Prospekt, and also offer full services for 2500 RUR an hour. Please note that not all massage salons provide full services (some will even be offended if you ask for!).
Some websites where you can find info on some other salons:

http://www.rusdosug.com/salons.php
Can't remember them all, but just do a search and you'll find tons of them (just remember that not all massage salons offer full services, so ask first before going there).
Salons are fun to visit, but you need to speak Russian.
