I stayed a week in Kaffee Kirsche's kiez between apartments and came in for coffee at least four…read moretimes. The lattes were great. The one time I got a flat white to go, it was just okay. I don't think the microfoam held up well in the paper cup. I didn't get a chance to do a pour over but they seemed to be popular.
They sell coffee roasted in-house. Depending on which roast you purchased, you could get some really fresh coffee. Some bags were marked as being roasted just a few days earlier but some were two weeks old.
I was drawn in the first time with their pastries display. They each looked so pretty. I ordered the strawberry tart. To be honest, I thought it was going to be strawberry cheesecake. I should have asked first! Instead, it was a strawberry gelatinous cream filling. The chocolate cake base was not rich enough to stand out next to the strawberry filling. I enjoyed the look of it much more than the taste of it. I've heard that the vegan chocolate cake is really the cafe's star dessert, so I'll have to try that the next time that I'm in the neighborhood.
I've never struggled to find seating, since it's ~2 blocks north of Kotti on Adalbertstr. The service can be unfriendly, which doesn't really match the look and feel of the cafe. It really depends on who is working, whether they're busy doing something else, and what language you order in. The first time that I visited, I ordered in German and the employee (possibly owner) looked really annoyed. Afterwards, I only ordered in English.
The prices are typical of an upscale cafe.
