Spindler is my favorite brunch stop when I'm in the mood for fresh eggs and classy but-yet-simple athmosphere. 

Secret place that is almost always empty.

Wim Wenders shot Wings of Desire here. It's a quiet place to work and definitely a gorgeous place to visit. Combine it with a visit to the Philharmonic, just across the street. Affiliation is 30 euros per year and you have lots of desks all over the library to choose from.

Osteria Sippi is an incredible simple italian restaurant where everyone feels immediately at home. They not only know their food game but have also an impressive range of really good wines.   

My favourite bar of the many around kreuzkölln is Bellman. After its sudden closure and reopening it underwent some changes and is boycotted by some of its former patronage, but for the less principled like myself it’s still a good place to go and they do pull the best Jever in Berlin.
