This is by far one of the coolest and weirdest passageways I've seen. For one it's completely covered and for two there is a bar situated in the most unimaginable of places. I guess it must be nice to come down from your flat to a hot cup of coffee. My friend and I have always walked by it and we finally decided to sit down and have a coffee. To my surprise it was actually nice cup of coffee. It was an experience for sure.
