Place is located wrong om maps and the name is now Zen zero caffé according to their Fb-page. It is right by Arnold Coffee on the corner. They serve typical café food, cheap cocktails also virgin style and different beer mainly german. None of the regular stuff being served in other cafés. I had a Schlenkerla Weizen there. Also three beers on tap. Staff were nice, smiling and helpful. Location is really great as it's tucked away from the most crowded areas. We were the only ones there in July and I'm guessing the regulars are mainly university students.
