The Zoo and the Aquarium is on the things that never changed during the years. Everytime I visit it looks exactly the way when I first went when I was a little child. This place gives me a lot of inspiration, I like the way they want to make the cage enviroment look natural with artificiel light.
A very close friend of mine owns this bar. It looks tiny from the outside, but it has two rooms you have to pass until you get to last one which is a discofloor. I play music there from time to time and I am always surrounded by nice people und friends.
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.
While strolling around Mitte, check out the flagship store of Berlin´s cult women fashion brand. (And try a delicious cinnamon bun at Zeit für Brot next door.)
