Everyone seems to rave about this place, and on paper it seems very nice, but I was kind of…read moredisappointed. I went there once for a coffee to stay, and another time for a coffee and a croissant to go. The croissant was a bit meh (maybe the solution is just not to buy croissants in Germany). The coffee was not bad but not exceptional either. And the service was a bit sketchy and amateurish. I have ordered a coffee in my terrible German, and the person at the counter did not understand me (this was actually the first time, there is nothing arcane in "a Kaffee bitte"), I had to repeat several times while she was giggling (gosh, people, try to learn a new language and we will talk again). Then they asked if I wanted milk with the coffee, I said a clear 'no', and they brought it anyways. Maybe this is some kind of supposedly 'friendly' (as opposed to professional) service, but I think I prefer the professional service that one gets in Parisian cafés (and okay, I was a bit offended by the laughing at my attempts at speaking German).
Maybe I will give the place another chance, because the Kuchen look rather tempting.
