Last Saturday I've been to SANSSOUCI Park in Potsdam, so naturally I have a few impressions for you.
The Dragon house. It is lovely to look at, but the food is overpriced and not good. I've had an Ice Coffee and it was horrible (watery and the icecream left a film in my mouth. ugh and that for 4,20€ I prefer any Starbucks coffee any time.)
Potsdam is definitely a city I could live in happily. Stuttgart and Munich would be my nightmare cities, because of the horrible architecture and the missing water and parks.
