How was this photo taken?

[Chris71]

I'm always intrigued as to how people manage to get such a broad range of exposure in night and low-light photos. Can I ask the pros here: How would you take this shot?



Is that HDR, post processing from a single shot or just clever exposure? How would I go about replicating it (minus the Trabants perhaps)?

So is it fair to assume it wasn't actually as dark as it appears when the shot was taken?
