Seconded: Glasgow also has some of the most amazing architecture, especially in the Park area [1].
I think a lot of the talk about the rough side of Glasgow has been overblown. Every city has rough areas and dodgy people. There are parts of London it's inadvisable to go out in after dark, in fact I've lived in some.
