Bikram Yoga in Beijing

Hi all,
I'm moving to Beijing in a couple of months and an internet search has found a studio that holds Bikram yoga practice just beside Xidiaoyutai station on line 10. Is anyone familiar with this studio? I'm trying to find out if it is reputable and what the cost is per class or if they do membership deals, etc.
Any advice would be appreciated.
Thanks,
Tess
