Exhausted after a 20 km run, we were looking for ice cream near HB. HappyCow showed us to this place and we were not disappointed. (Although "near HB" might be an overstatement, it is definitely within walking distance.) The ice cream comes in about 15 flavours and you can taste them to help make up your mind.
During our visit, most tables were occupied by other visitors, most of whom were attending the vegan buffet. It looked good but we didn't try it.
