Added amenity=toilets as there is a public restroom available.

Allianz Global Corporate & Specialty SE - campus Unterföhring was missing in the map.

Added alternative name.

Drove there recently; we were looking for the Fanja Wadi entrance and did find it asking locals. Thus I decided to add it to OSM.

Based on this information: https://g.page/Kaffeeart

Just biked today here. There is a free drinking water fountain below the observatory.

This way does not exist anymore. Only the paved street (Sattelweg I) is maintained. Did walk this way last week and used OSM.
