London

Was in London last week. First thing you want to do when you get there is get yourself an Oyster Card. Far as I can make out, it's a smart card that you top up from time to time. Best part is that it calculates your journeys, so you never end up paying more than the cheapest fare you were entiteld to if you had bought it at the start of the day. So for example, if you would have been better off buying a day pass. And even better, bus journeys are a pound a piece. Be careful though, it is not for use on some Thameslink services despite what a bearded eejit at King's Cross station might tell you. While I'm on the toursit advisory board here, you can pick up a sim card from Carphone Warehouse for ten pounds, so bring your phone.

Other things to do: get yourself a can of Carlsberg Special Brew (or some less plebian equivalent), head into Regent's Park with a good book (eg Peter Carey's Theft), and prop under a tree for the afternoon.
