As a student of history I'm quite familiar with the British and the war musuem. But I was also thinking of doing some more different things as well. However as I'm going with my gf, and she has yet to see London, we'll go to some classics like tower as well.
Things we'd probably do:
Tate Modern, the British museum (as it's free anyway no?), A bicycle tour through London, going to a musical, Harrods (you know women...), Picadilly, probably wander around at some places like nothing hill (she's Hugh Grand fan gah! Though I bet the war museum would be wast of our time gah!

)
But I'd also like to do more different things (which don't include prostitutes) and as Louis said it: "barge in and soak up the atmosphere". That and try to stay away from shops and shopping streets and malls before it's too late.
Going to see what this dickens tour is.
Of course more suggestions or tips are still welcome!
