Secret, sky-high views of the Sony Centre
The spectacular Sony Centre at the heart of Potsdamer Platz is easily one of Berlin's most popular attractions - so much so that it's hard to believe it could possibly harbour any secrets.
But we're pretty sure few visitors realise there's a sky-high café hidden right beneath the famous, circus-tent-like roof. And the views from its ninth-storey terrace are, of course, very special indeed.
The Helene Schwarz Café is part of the Deutsche Film- und Fernsehakademie (German Film and TV Academy), and although it's mainly used by students, the public are also welcome to drop by for drinks, snacks and reasonably priced midday meals.
Knowing about this hidden gem isn't exactly easy, however, as you can hardly see it from the ground and there are few signs advertising its presence.
But take the lift serving the Film Museum and Academy up to the 9th floor, and you'll find entrances to the canteen as soon as you get out.
Quite literally a top tip.
Helene-Schwarz-Café: Potsdamer Platz 2, 10785, Berlin.
Take the elevators used to access the Film Museum to the 9th floor, then turn right or left.
Note that the café keeps academic hours, and is only open Mon to Friday 8am-4.30pm. Lunches served from 12pm-2pm.
