The order rate of hot and sour chicken offal is also quite high, and unlike traditional Hunan cuisine, the only best sour and hot chicken offal only uses chicken gizzard as a main dish, and the sour taste is heavier. The chicken gizzard is chopped, and the parsley ginger slices, chili pepper pickled pepper and other fierce fire are fried, the flavor of the seasoning is gradually mixed with the chicken gizzard through the fire, and the chicken gizzard is crispy, sour, hot and salty. The preparation of the two signature dishes is not complicated and superb, and even has some casual home-cooked dishes, but the unique oily and spicy Hunan cuisine attracts Hunan people to sigh that the taste is authentic, and Xi'an diners are very amazed, and the aftertaste of the food is very good.

The founder of the restaurant is from Youxian County, Zhuzhou, Hunan, so it uses ingredients such as hemp duck, fragrant dried meat, bacon, and dried meat from Youxian County, which is authentic. Youxian fragrant dried taste is smooth and tender, tough enough, the only best to stir-fry it with lean meat, parsley, green and red peppers, etc., the dense and crispy fragrant dried pepper wrapped in meat pepper spicy, home-style flavor is strong. Dried meat is a special product of Youxian County, the pork belly is pickled for a few days, sliced and wrapped in rice flour and then air-dried in the sun, and then smoked with toon wood. The only best will be fried in the sun, crispy on the outside and fat on the inside, but not enough to taste, a little greasy.

There are a total of 6 branches of the only one, and the main store in Dongsidao Lane is the most recognized store for regular customers. The environment of the main store is rough, the lights are dim, there is a sense of crampedness, and the waiters are mostly middle-aged women, and the attitude is not enthusiastic, but the hands and feet are nimble. During the peak period, the dishes are served slowly, and many dishes are fried in a large pot and then divided into bowls, which is criticized. The only best basically uses a white porcelain bowl to serve vegetables, not only has no appearance, there is no plate at all, and even the vegetable bowl is bumped and broken. The environment, tableware and service are all average, but it does not hinder the popularity of the unique one, the authentic and spicy taste attracts countless diners, and the meal has a large number of queues, and table sharing is quite common.
