... assuming you already have the Tower of London on your list (and who wouldn't? Crown Jewels!), my main recommendation is the Monument. Climb it and look out over London!

... assuming you don't mind 311 steps up (and down again), that is. Strangely, most people object.

I'd recommend checking out what West End shows are on if you're at all interested in that sort of thing, if you are it'd probably be the highlight of your time in London.

Go to the British Museum and the Victoria and Albert (I don't really like art museums but I still enjoyed it). Those were by far the best things we did in London (the Rosetta stone!).

The second best was that my mother and I made an effort to take as many tube lines as possible. I think we only missed one; two tops. But that is probably more to do with my love of public transportation.

'The minimum age for the purchase of alcohol is 18. People aged 16 or 17 may consume wine, beer or cider on licensed premises (pubs/bars/restaurants) with a table meal. In England and Wales, it must be an adult who orders,[72] however an adult doesn't have to be present to order alcohol with a meal in Scotland. The legal age for the purchase of alcohol from an off-licence (store/supermarket) is 18. (The legal age to buy liqueur chocolates is 16, but this is rarely enforced.)' From Wikipedia.

• The London Eye is always worth a go if you hadn't thought of that.
  + A couple of companies do short (hour or so) cruises down the Thames which are quite nice as long as it's not raining!
  + Camden Market (http://www.camden-market.org/) is great if you're into 'alternative' stuff (read: geeky weird clothes! :D)
  + There are two 'Heritage' bus routes (short sections of the 9 and 15) that are operated by the old 'Routemaster' buses.
  + The London Science Museum in South Kensington is great if you're a science nerd (like me!), and there's the Natural History Museum right next door too.
  
  That's all I can think of at the moment, but I might come up with something else later! You'll love it, trust me! (yeah, I suppose I am biased :P)
