yes it is expensive. but in relation to where?

cost of living etc in the US is cheaper but the bars and clubs arent, not much anyway - and the cabs cost loads which you have to get everywhere cos the public transport sux (i'm talking about LA here)

i can think of many places more expensive than London:

Hong Kong, Tokyo, Stolkholm, Paris
any capital city is gonna be expensive so in relatively speaking london aint that bad
