Things to do & see in London

Have you been to the Whitechapel Gallery? I'm planning on heading there on sat.
Or maybe even Camden - I can't stand it on a weekend, but on a Friday it might just be tolerable, and maybe even enjoyable?

Are you ready for a confession: I'm a crap Londonenger, not been further East than Chancery Lane, or further North than Euston in over a year, so for that reason alone Whitechapel Gallery sounds good, thanks!
