"A bottle of Water someone bought cost £12."

More fool them!

I live in London and while I think that some of the more touristy spots (Leicester Sq for example) are pretty nasty it is, on the whole, a great city.
Good advice about the bus – I get the 274 often!

If you're interested in old places, there is a great wine bar called Gordons Wine Bar on Villiers Street, beside Embankment tube station which is a really unique place and in my opinion a must see.

There is a very healthy live music scene and you'll easily find acoustic music around any night – there is a very good bluegrass session in my local pub (the Hemingford Arms, Islington) on Mondays.
