London is interesting, in that the square mile (financial district) while being very busy (even at night) during the week, due to workers drinking and socialising after office hours, is absolutely empty at weekends. On Sundays the streets are absolutely deserted, which makes it a great time to film apocalyptic zombie movies - see '28 Days Later' for an example.
