I was gonna say that Glasgow city centre is pretty atypical - resembling US cities close enough that a few parts of World War Z (which were meant to be Philadelphia I think) were filmed there. But then I realised that Edinburgh's "New Town" (actually hundreds of years old) is a grid-layout too.
New Town in Edinburgh and the modern city centre of Glasgow both date back to the mid-18th century. They're very unusual for the time insofar as they had a large plan for a large area.
