There are loads of places in Berlin that serve brunch, but my all-time favorite place to go with friends is Allan's Breakfast Club aka ABC. This tiny french place owned by the super french and super cool Allan is not only cute, but serve the meanest eggs benedict in town. It is situated in the heart of Kollwitzkiez in Prenzlauer Berg and just some minutes from my flat, very convenient.
Here you can find all the restaurants I visit and frequent. From Berlin to Helsinki and from Oslo to Lima.
