Well, if you are an ice-cream lover like myself, there is only ONE place to go.
At the Potsdamer Platz Arkaden (a big shopping mall) there is an ice-cream place on the second floor that will not disappoint you.
By the looks of it, you'll think it isn't much. It looks like any other mall café. But the ice-cream... oh, lala.... it's to die for.
My husband and I ate until we could eat no more. And believe me; they tasted as good as they looked.
