Kiez vegan has a great selection of fresh salads, plus mediterranean bakes like börek, pizza etc., which you can get heated (microwaved...) or take out in a paper bag. Some fruity cakes, too.
You can mix and match the salads as you like; when we came with three people the owner suggested to make us a big plate with some of everything - a great option! The quantity was really good, too. There is a small sitting area inside, and very nice outdoor sitting on the wide pavement (in a quite quiet road).
Doesn't serve alcoholic drinks, only soft & hot drinks.
Cons: Small place without bathroom
