Kind of similar atmosphere and both are located nearby.
The typical Kreuzberg bar, relaxed and very casual, good food.
Kind of similar casual vibe, but Morena is a bit more into trendy stuff, while Hurwundek is really just down to earth.
I'm sitting in Morena now and there's as many people with laptops as in Sankt Oberholz.
Although Morena is more family oriented and doesn't host concerts, Cafe Dada reminds me of a typical cool local Kreuzberg bar, which Morena is.
