I went to a Kundalini yoga workshop with US superstar Gurmukh who is in London until Sunday, go and see her as her workshops are legendary!
Kundalini yoga is not for the faint hearted: along with the meditation, there is a lot of hard work involved but it is one of the best types of yoga to free up your spine. We also had a little boogie at the end with some drumming music while downstair in Kingly Court you could hear the Friday revellers laugh over a few pints at the pub!
I really liked the venue, the main yoga studio was opened up (it has a sliding partition in the middle) as there were so many of us, I didn't count but surely at least 50 participants. There's also 2 treatment rooms which I didn't see. The studio has skylights and has a very bright and airy layout being on the top floor. Incense and candles were scattered around the room which made it very welcoming and conducing to meditation.
I could see that the staff were a bit overwhelmed by how popular this workshop was and reception was heaving, but they handled all enquiries and the registration process with extreme poise (I bet they do yoga too!).

Very happy to recommend both Triyoga (but this place doesn't need publicity, it's so famous!) and of course the wonderful Gurmukh.
