The restaurant is sitting in a rather quiet zone (I didn't find a busy area in Berlin anyway).
Portions are not abundant to be kind and service is very sloooooow.
Indeed you don't taste often flavors combined like this, but it's not worth the final bill (€ 60 per person for a 3 tiny courses menu). Deceiving
