Green. I’ve said it before and I say it again, Berlin is very green. Trees everywhere, offering lots of shade and making the urban air somewhat breathable. If I were in charge, meaning if I were either God or Donald Trump, cars would be forbidden altogether. Except maybe for Aston Martins, Bentleys, and la déesse. But that’s a completely different story. Anyway, on a hot summer’s day, Berlin’s trees provide enough shade for strollers and flaneurs to survive global warming, its architecture offers some diversion, and in the same spirit, its restaurants are contributing some nice sunshades to dine under.
