I went there with a friend and we were glad we found a seat, because this place is crowded at the weekend. The cakes are almost unreal - some are plain simple like brownies, some are extraordinary like cherry cream or Manner (vegan waffles) cream cake. It is also one of the few places that sell macha latte.
It's a cosy place where you can spend some hours, eat and drink or have a quick read through one of the books that are displayed on the shelves.
Cons: self service with long waiting time
