Speaking of Neuer Garten in Potsdam I forgot to mention an important building there in
my post below: the
Meierei. In this building used to be the diary-farm of Cecilienhof palace. Then it decayed for many years because it was located in the nomans-land between East and West and the was no public access. Ten years ago someone bought it, reconstructed it and runs it as a restaurant and a micro brewery.

It's not easy to get a seat there but it has an amazing lakeview, the fish meals are delicious and the freshly brewed beer is simply great after a hard day walking in the park :-)
