Dorner is very popular in Germany. This is a Turkish China hamburger. Prices range from 3 to 5 euros. Baked bread is outside, and you can choose the meat stuffing and ingredients inside. There are usually chicken, beef and mutton. It can also be paired with raw onions, various salads and carrots. . . It is also served with yogurt sauce, hot sauce, salad sauce or curry sauce. I liked it very much when I first went to Germany. Later, I went to Istanbul and found that there were few Dorner sellers there. It's like Peking Duck in China. The Germans thought it was all over China.
