You can visit depending on where your passport is from. I know you can't normally visit with a US passport, I'm not sure who else is barred but Europeans are usually fine.

It's more normal than most people expect, there are a lot of videos these days. Not a lot of private cars, people in the city mostly travel by public transit (buses and subways). There are parks, water parks (I am bothered by there being a rock climbing gym in one), fried food vendors, karaoke, etc. It's nice to see since I used to think it would be more 1984.
