I celebrated my birthday here on Sunday afternoon with a total of 14 people. The coffee was very tasty and everyone enjoyed the various cake and tart creations. I also think the vegan and gluten-free alternatives are great. The prices were absolutely fine. The employees were also friendly and personable. The rooms are very inviting and decorated with lots of plants.
It was very busy and the self-service meant there were longer waiting times at the cake and coffee counter. Unfortunately, we didn't have enough chairs at the beginning. There was also no table so that everyone didn't have to squeeze together to eat their cake. Since you can reserve online for up to 15 people, I assume that this should work. Therefore a star deduction for me.
Nonetheless, I would definitely come by again, but probably not with so many people :)
