Dandan Noodles is a famous snack, which is deeply loved by Sichuan people and has a unique flavor. Named after being often peddled by vendors. This noodle is red and bright in color, fragrant in winter vegetable sesame sauce, hot and sour, fresh but not greasy, spicy but not dry, and can be called the best in Sichuan pasta.
In fact, there are nearly 100 kinds of noodles in Chengdu, each with its own flavor. I saw an introduction about Chengdu cuisine in Weibo, which was very good. If you go to Chengdu, you must look ahead. The introduced address is in the reference link. See for yourself.
