I've been overwhelmed by British accent so far. I don't really grok what people are speaking!
Other than that, it looks like London is a lovely city, but not so good to actually live. Everything is damn expensive! 3 stops subway ride is 3 GBP (= 5.6 USD), 24 hours internet connection is 10 GBP (= 19 USD) and Starbucks tall frappuccino is 2.9 GBP (= 5.4 USD). WTF.
