Germany’s first concept-mall can be found between the redeveloped Zoologischer Garten area and the ultra-hip 25 Hour Hotel. Occupying a recently refurbished 1950s building, its slickly reworked interior now houses flagship stores, quirky boutiques, and outlets from local fashion designers, as well as trendy coffee and snack stalls and healthy smoothie shacks. A wide staircase takes you up to the roof terrace where you can stroll and check out the monkey enclosures in the adjacent zoo.
