I have actually been meaning to try this place out for weeks, unfortunately haven't had any time til today.
Name: FengDingYuan Sauna
Location: 580 Nanjing Xi Lu (West Nanjing Road), at the corner of Chengdu Lu, inside Nanzheng Da Xia building, block B (where the fake market is located).
Price: 630 during the day, 680 in the evening (as mentioned in a previous post)
Ok, so the place was a little bit of a pain to find. The Nanzheng building is actually 2 buildlings, the main one being an office building, and off to the left-hand side is the fake market building. Once you enter the fake market from the Nanjing Xi Lu entrance, do not take the escalators, as they only go up to the 4th floor, and you want to head to the 6th. Stay on the side with the Bank of China, and walk all the way down to a small lobby with elevators. From there, simply take the elevator to the 6th floor and you'll be met by the attendants.
I went in at about 3pm, and there was a fishbowl of about 8 ladies to select. Unlike a few other saunas, they actually have uniforms, so its hard to get a good look at their figures. Looks ranged from 6-8 though, not as hot as some of the ones from 999, but definitely better looking than G18. Anyway, after picking one of the taller ladies, was led to one of their rooms (I was really struck by how HUGE the inside of this place is) that is pretty similar to the 999 smaller rooms. Anyway, everything was pretty standard (no soapy, just a shower). I was a little disappointed when my girl undressed and I found out that she was even flatter than me (damn those uniforms), but she made up for it with her enthusiasm. Finished up and paid the bill (630 RMB, as mentioned above). The time frame is an hour.
Anyway, just a pretty standard setup at a great price. Would definitely recommend it now that 999 is gone.
