When I lived in Bremen in 1960/61 there were little carts everywhere with long skinny crispy bratwurst served on tiny bun in the middle and little papers of mustard. They were incredibly tasty and I have never found anything like it since. Is this still a thing in Germany? And particularly in Berlin where we will spend a week this May. If not on the street, any recs for great German food here?
But I really want to find that wonderful old street food.
