Glad you enjoy London! Remember though re: price of stuff, that London is pretty much ridiculously expensive compared to the rest of the UK. A job that pays you £20K a year would pay about £23K in London because of the mark-up. EVERYTHING is stupidly expensive there.

Minimum wage in Britian - depends on how old you are. I think up until 18 it's something like £4.90 an hour, and after 18 it goes up to about £5.20 an hour. It's around that area. But I don't know the exact numbers.
