You've been there already because Kaffeemitte is no secret but anyway, I like it.

And to the anonymous reader who gently prodded me to say more: Because I'm a sucker for concrete and irises, because the espresso is affordable and not too acidic, because before there was nowhere else around Hackescher Markt I wanted to go when I wanted cake or small snacks.

Kaffeemitte, Weinmeisterstr. 9a, Berlin-Mitte (map)
Open M-F 7:30am-10pm, S-S 10am-10pm
