How do I make cool friends (25-35 ish)in London?

I am fun, confident and I love dancing and talking. I am considerate, a good listener and a bit mischievous. Basically a fab friend. I recently moved to London and all my mates are so far away. I'm on a training course but seem to be surrounded by people who have children, religious commitments or are on Masters courses. They are very nice people, but I have no-one to rebel with. Any suggestions?
