Ok, just a word up front. I am not a vegetarian or vegan (but massive foodie) but my partner is a vegetarian (sometimes ;( - but not at kopps!) Meat eater or not, you should come here!
One of the best veg friendly restaurants I've been to ever (probably tops vanilla black on London and better value! And possibly even shakahari Melbourne ) [nb is vegan but you could bring a meat lover and i barely think they would notice!]
We came here twice, once for Christmas day brunch and also for dinner! Contemporary cool decor, warm friendly vibe and the best food ever! Frequented by local cool Katz, awesome cocktails coffee and bar to boot! (equal to Melbourne standard coffee)
For example for dinner there was beet root carpaccio with almond cream a caper berry and deliciously surprising deep fried capers, a red lentil soup (delicious) with a cinnamon foam and giant rustic has brown type crouton, for mains walnut risotto with pumpkin and pickled cherries, chestnut ravioli with endive, roast apple and potato other delicious goodies! We did not have dessert (too full) but observed others, creeps suzette and various chocolate and nut based delicacies!
Brunch included waffles delicious pancakes various innovative salads and hot meals!
Seriously, don't leave Berlin without trying kopps!
