Zola is a Neapolitan style pizza joint hidden inside a Kreuzberg backyard. This is a killer pizza place, one of the best in Berlin without a doubt. 

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.  

My favourite book store with a minimal interior and maximum range of books on architecture, design, art, philosophy and politics. 

Beautiful atellier-stores around weserstrasse, this is from a very nice girl that make "sculpure hats" as she said. Excellent record store across the street also.

Italian Cuisine with a modern twist in a cozy atmosphere. Tip: Try the pasta with figs.
