Starbucks and social studies. Seems you can judge the area you're in, or at least get a fair feel of parts of it, by what's pinned on to the community notice board in Starbucks. On the board in the Holland Park outlet alongside the corporate in-house bulletins are flyers for yoga, dog-sitters, open air-theatre and so forth; slap in the middle of the board in the branch outside Kings Cross station, on the other hand, is a £20,000 reward notice from the Police for anyone who can help in solving a murder.

Yep, completely unscientific, derisorily small sample size...but I know what's going to happen: more dishwater coffee bought simply to see what's on the community noticeboards.
