London by night - beautiful, magical place of wonder.
I've also discovered that walking around the city, when only the commuters have come out to play, is much, much nicer than when the place is crowded with tourists. The rush away from public transport, however busy, seems organised and therefore much calmer. The other morning, bright and early, I went for an hour and a half walk from London Bridge to Euston Rd, sipping on a free latte shot, eating doorstep toast and chatting about everything and nothing. Much nicer than the 5pm rush I must say!
