Flughafen Tempelhof was once the symbol of nazi-pride when Hitler notoriously comissioned construction of the smallest duty free shop in the world (and a beautiful example of fascist architecture). After the war, Tempelhof became one of the frontiers of the cold war with the U.S. battling the communists (who undoubtedly wanted to get rid of the small duty free shop altogether) via the Berlin Airlift. It turned out to be a huge succes, and enabled the allied forces to remain their presence in Berlin and save the small duty free shop. The real free-market victory will come in about two years though, when project developers will take over and start building houses, blocking my view onto the airfield.

Taking a little sun and walking around Paul Linke Ufer is always a good way to spend the afternoon and recharge batteries.

Tuesday's lunch hour tip is the amazing Berlin Philarmonic. A short-duration concert (around an hour) happens every Tuesday at 13h, for free. People make the Philarmonie's foyer full, sitting on the stairs, on the ground and everywhere around. Little advice: bring with you a little cushion for more comfort and try to arrive early to find the good spots.

The Cô Cô bánh mì deli serves great vietnamese sandwiches and the best lemon grass tea I've ever had.

The typical Berlin winter is biting cold and grey. In combination with the hardness of the city and the angry natives, it feels like a hostile area. Why it's worth experiencing it? Because that's the way this city is.
