I was rewarded with that opportunity yesterday.
Do correct me if I'm wrong, but Rivington Street seems to me to be the mecca of street art in London. The first thing you notice when you enter the street from the Shoreditch side is Eine's famous (or infamous, depending upon how you're inclined to view street art) typography. It transforms the underside of this bridge from a dingy stinky passageway into an art gallery in its own right.
