The sheer arrival alone is a stunner. After leaving the glass elevator, you promptly get a first impression of where you'll be spending the next few hours: over the rooftops of Berlin. If you don't feel like enjoying stained salmon or marinated mushrooms just grab a cocktail at the bar, climb up the flight of winding stairs and drink a toast to the night sky. Overlooking Berlin's full panorama on a comfortable couch or swaying gently on a swing is hard to beat.
