Probably obvious - London Stag Do Ideas

[Zippee]

I know London is probably one of the easiest places in the world to sort out a stag do for but I'm stumped.
I need to organise a stag for 10 people in London towards the end of Jan next year. Start on a Friday evening and ending Sunday.
Friday evening I thought about starting in the Vodka Icebar and moving onto a few pubs/clubs but Saturday I'm a little unsure about.
What to do during the day and where would be fun/cheesy for the evening where I can get the stag dressed up and we can all just have a laugh?

I don't know London at all well from a social aspect so any ideas welcome!
