Best coffee in town, no question. I highly recommend their Cortado and Latte.
There are perhaps less than five places in Berlin where espresso lovers can actually drink coffee properly. Freshly ground beans and carefully poured extractions are not exactly common amongst a sea of generic Bäckereien and Kaffeemaschinen.
Just as you would hunt down the best Cantonese food by looking for the places where the old Chinese people frequent; so too with the best coffee — look for the place where the Italians, Australians, and New Zealanders frequent. This is it.
They serve great Flat Whites as well as everything you’d normally expect, singles or doubles. Counter food is limited to Kuchen — the carrot cake is as good as you’d find anywhere. The place is small — more an espresso bar than a café per-se, but the home-made outdoor furniture vibes perfectly with the surrounding street. Both staff and customers are super-friendly.
