Live in London right now. If you can get the iPhone app called tube deluxe, it will help you get around London. You can also check jptube.co.uk, but the app is much better. Another app that I find helpful is travel deluxe (icon is the red double decker). You just put your location and where you want to go and it will plan your trip for you. Or, I could ask a private taxi for you as to how much it will cost to take you to st. Pancreas, they are generally cheaper than the black cabs.
Where are all the materialistic people?!
