Cosmoveda is a hidden xberg gem. It's an Ayurvedic supermaket that happens to come with a kitchen with it. There you can find a delicious Ayurvedic lunch menu (with soup, main and a little dessert) in 3 different sizes, prices starting at just 5,90. Not to mention you can shop the ingredients that you just ate in case you want to try to cook Ayurvedic yourself.  

I never knew this neighbourhood existed and went to visit a friend and was instantly transported out of Berlin into some sort of 50's utopia. "The Hansaviertel is a prime example of modern architecture and urban planning in the fifties in Berlin. 36 individual buildings or ensembles still form the model of modern architecture and urban planning of the 1950s. The southern part of the war-damaged Hansaviertel, which lies between the S-Bahn line and Tiergarten, was chosen as the central demonstration area of ​​the International Building Exhibition in order to present the "city of tomorrow" - in deliberate contrast to the East Berlin Stalinallee and the restored tenement barracks." - berlin.de Also visit The Akademie der Künste, if not for the art then the architecture alone.

Besides being the friendliest shoemaker in town, he also offers quality for good value. 

New type of museum. It's a private collection from contemporary art pieces such as by Anish Kapoor or Nobuyoshi Araki to Chinese imperial furnitures or ancient Asian sculptures. The collection is wonderful and the light design is perfect. There is no description or title of the artworks - it invites you to purely see/feel the artworks themselves without influencing by the names. Must to go.

My favorite lake to visit during the warmest months. It's located in the southwestern part of Berlin and it's reacheable by public transportation, just around 40min from the city center.
