First we went to eat the best Döner in Berlin (believe me it is the best) on Mehringdamm 32 (just some steps away from Curry 36).
After this delicious meal I guided her to a vegan cafe in Neukölln.
The cafe Vux is small and well decorated. The atmosphere is pleasant and the cakes are very delicious. I couldn't believe that those are all vegan, because I ate "normal" cakes, which weren't half as tasty.
If you are in the area stop by, take a break and try one of their cakes!
