The only crown of this "square like" urban space is "Crown and Anchor" pub! This types of public space is essential in any big city.
In this case it is almost totally pedestrianized, but organically. Streets are not closed for traffic, traffic is just forced to avoid spaces like this and it is to the benefit to all of us. Way to go!
Photo bellow left is from one more connected pedestrianized area nearby. Also very good example of what can be done for the city.
