Not matter where it exactly is from, Döner places are at nearly every corner in Germany and are already considered German food by many. It consists of often pita bread and filled with ingredients like for example meat, lettuce, onions, tomatoes, feta cheese and a sauce (e.g. garlic sauce, hot sauce...). There are hundreds of variations to it though and the ingredients and sauces vary from restaurant to restaurant. It also can be sold as a Dürüm, rolled in flatbread (for example Yufka)
