Pretty poncy things really.
I was a member of this one- http://www.oxfordandcambridgeclub.co.uk/
I considered joining this one, but it is just SO twee- http://www.caledonianclub.com/
Some of my creative friends are members of these (I wouldn't get in. I'm too boring and corporate)-
I had a free membership for a while at Quintessentially Soho, but I didn't renew it when it expired (ridiculous £$£).
Do you ever see yourselves using one of these things? What would be an idea for a good new club? Are they basically a bastion of all that's wrong with society?
I think my problem with them is that, unlike Groucho Marx, I'm not really turned on by exclusivity.
