Foundation, some kind of bio-, anthroposophic'ish church, with various facilities attached. Seems…read morelike a religiously-centred community, with a Heim (orphanage), therapy centre, etc. with this nice attached cantine.
We had the leberkäse, and the milchreis; one each between both of us. This is therefore highly recommend as a peaceful eating area, with delicious food.
It was the best milchreis in ten years, flavourful without a hint of artificial ingredients. Berries adorned the top. The rice was crisp slightly, perfectly-prepared.
Each staff member clearly had the highest professional standards; service was excellent - one is expected to handle one's tray, as it is cantine-style and not a restaurant per se, yet it had every other amenity. Which made handling trays enjoyable, in a different way than ordinary.
We have not walked the grounds, yet. See the photos as part of this review (german).
