Time Out says
Bring your table tennis bat and prepare for ping-pong madness. The action doesn't start until around midnight, but when it does you can expect 30 or so players - some good, some bad - to surround the table. Beer, soda, tea and juice are available, and sometimes cakes or pastries, but otherwise there's no food. No tables, either. Just a bunch of chairs and two couches in a smoked-out, garage-like room. All in all, it's lots of fun. Note that the opening hours are unreliable.
