Katz & Maus is a cafe/bar at Circus hostel in Berlin. Cafe is located at the ground floor level and the bar in the basement.
I discovered the place through one of their regular 'Meet the brewer' meetups. There was a presentation about the beer making process done, as the name suggests, by the brewer working there. Bonus points for the complimentary beer samples :) I especially liked the house Ale (regular price 0.5l for 4 Euro).
The bar feels extremely 'hostely' - plenty of backpackers and lots of conversations about travels. Very easy to meet other people.
It's a good place to go for a drink when you feel travel sick. read more
