Berlin

We'd said we would postpone research for the European leg of our journey since it's already familiar and "easier." However, Atlas Obscura recently posted a piece on "hidden attractions and unusual things to do in Berlin" so I've decided to capture it now. We've already decided to put Berlin in the Top 20, so this post will focus more on what we might want to do and how long we would want to stay there.
