I am looking into enrolling in a beginner's Yoga Class in Wimbledon. Reviews of Raj, the owner/manager of Hot Bikram Yoga in Elm Grove are pretty damming (the rather biased "review" site called Yelp.com). There are two OK reviews, but both very old. It seem odd that this place does not have more positive feedback. Does anyone have any personal experience of this place and, in particular, of Raj?
