Oslo, London and Copenhagen: The world's three most expensive cities
Thanks to a weak dollar, US cities like New York -- which made the 18th spot -- have moved down on the list compared to last year's; in fact , compared to the same study in 2006, London was noted as 26% more expensive than the Big Apple. In Asia, Tokyo ranked the most expensive followed by Seoul, Singapore and Hong Kong.
So where do you go if you want the biggest bang for your buck? Kuala Lumpur, Buenos Aires, or Mumbai, which ranked the three cheapest cities for visitors.
