Expensive?

I've started to read The Economist which I have to recommend as being one of the better bastions of journalism around (yes I know all you regular readers of it know that already, but many don't!). One thing that got my eye in the latest edition was this article. Basically it confirms what I've been saying for some time, that London is one of the most expensive places in the world, certainly more expensive then the places that typically thought to be more expensive (NY and Tokyo being the main culprits). Coming in 4th it was notable to me that 2 of the cities more expensive then London were Scandanavian (Oslo at one, and Copenhagen at 3rd).
