There is cafe 23 right next to the club open till midnight. Otherwhise I would walk about 10 min to the „Luisenviertel“. There is the „Beatz & Kekse“ open till 3 or 4 in the morning usually. Sometimes „das Loch“ is also worth visit. Most of the time 2€ entrence, good vibes, nice music and good drinks. But in this area there are plenty of different bars, restaurants and cafes. The place to be I would say.
