You can watch people live, having fun and generally playing havock with the London traffic.
A constant stream of photo shots, it's the one crossing to avoid in London if you drive.
It's also the one crossing where most pedestrians don't want the traffic to stop for them
so they can get a clear road for that photo.
Can't complain though; I've done it myself!

Left my mark on the wall too. Unfortunately it's painted over every month.
