NAMES AND NUMBERS
– always check out the Museum Island when in (especially new in) Berlin. The New Museum and Gallery Bastian at the Kupfergraben both by David Chipperfield Architects are amazing and worth a visit.
– There is also a great design/art/architecture/photography specific bookstore right by the Museum Island which I loved checking out (http://www.buchhandlung-walther-koenig.de)
– the Alte Schönhauser Straße is one of my favorite streets for shopping (Germany's first Aesop store and a store with those amazing sunglasses that I have been wanting ever since I saw them) and there are great cafés and restaurants nearby and along it.
