Berlin-good restaurants and beautiful castles

Esmeraldas peruanische Spezialitäten is a very nice Peruvian restaurant in one of Berlin's nicest districts called Schöneberg. Especially in summer the place is very enjoyable with its nice terrace to have a Pisco Sour, Ceviche, Causa and Pollo a la brasa which are most recommended to try out at the restaurant. There are also more things to try out such as the homemade ice cream with special flavors like Guanábana, Guayaba, Lúcuma or Chicha morrada. If u have more time it is also really nice to walk around the area and you can always have a cheap beer from the Späti and enjoy it for example around the Apostel Paulus Church where in summer lots of people are sitting and hanging out. 

Potsdam is a bit smaller city next to Berlin and is known for its castles that you can find at Park Sanscoussi where the University of Potsdam is also located. It's is really nice to take your time and have a chilled walk through the park because it is really huge. But not only the castles are a must see in Potsdam. Also the mansions in the hole city are very nice to watch. It's a little insider tip because it is not an official tour but just go through the city and enjoy looking at the mansions and get some Beverly Hills feeling in Germany.
