Exchange Square lit up nicely during the lighting tour that we had after work (basically we were looking at good and bad examples of lighting, for example whether it lit the place up well without being too intrusive.
Two of the guys with us decided they were hungry, and went off to get food. After a while, we saw them standing on the other side of the street, just watching us. They eventually showed up at the pub, complaining that they thought we'd cross the road towards them.
