There's actually a good collection of embassies around. But the most interesting link with Potsdam's diplomatic history is probably the Russian Colonia Alexandrowska, that is a set of about twenty houses built in the early 19th century to house a group of Russian singers sent as a present (!) by Tsar Alexander I to king Friedrich Wilhelm III. Here's one of the houses, that seem to be very well mantained:
We must also give a culinary recommendation. Probably the best is to walk around Nauener Tor. We stopped in Benkerstrasse at Maison du Chocolat where, naturally, we got hot chocolate. It was thick and good, reminding us of the excellent chocolate you can get in Pretixol street in Barcelona. And they also have a nice selection of home-made cakes!
And after this ingestion of calories, go burn them with a walk around the gardens of the famous Schloss Sanssouci.
Finally, a challenge for the visitor. Find the Branderburger Tor in Potsdam, and compare it with the more famous one in Berlin.
