Back in the day, this was one of East Berlin’s most popular cafés. It has since been renovated, but still retains some good old Communist charm. What’s really interesting, however, is the small exhibition documenting the history of the Karl-Marx-Allee. There’s also a terrace offering splendorous views over Karl-Marx-Allee, but this must be booked in advance.Open daily. Terrace visit: €15 for up to 5 people, €3 per additional person.
