A very good reason to travel West: the C/O, next to the formerly infamous Berliner Zoo tube station, is an awesome museum dedicated to photography and visual media. Previous exhibitions include Larry Clark, Martin Parr, Anton Corbijn, Annie Leibovitz and Stephen Shore.
It is an English language bookstore centering on non-western, diasporic, and queer perspectives.
Many many many rare and special books carefully selected by Siddhartha Lokanandi that is the soul of this place! Check it, it is unforgettable :)
