I want to take my 22 year old son out in London for a good weekend.?

No visiting monuments!!!! Only enjoyment!!!!! We'll start around 10am 22nd January 2011 and finish in the wee early hours. He's a bit of a raver. 'Illegal rave parties' they're called abroad. Any suggestions???? Shops,markets,pubs,concerts, etc. I'm not old don't worry I like to enjoy myself. :)
