I went a couple of time to the one close to Nanjing donglu station: they always asked me if I wanted a man or a woman.
And the 7 star masseuses are really really good.
I recommend the place, at least as an alibi: nobody would believe that your never tried massagein Shanghai, so you need a legit address.
I went to the shop on Nanjing East Road. Decoration of the club maybe much more caters for men's tastes. The place is clean and dark. Receptionists are professional and enthusiastic. I asked for a 60min full body massage, but 50mins pasted, my therapist was still working on my back. The whole massage took 90min and the price went from 60USD to 100USD. Though the massage is good, I feel ripped off! For that reason I won't go back again.
I have been there twice. I have tried 60mins foot massage and 90mins body massage for less than 600RMB. Really worth the price! The place is clean, safe and comfortable offering really proper and professional massages. I fall asleep during the massage. Really a great experience.
