Liu Yiwan, like Yadebao, is a duck blood vermicelli soup with a thick soup pie. Although the name of the restaurant is duck blood vermicelli soup, there are also soup dumplings, wonton noodles, dandan noodles, wontons, beef noodles, and some desserts.

Liu Yi's bowl of duck blood vermicelli soup, the soup base is boiled with kelp shreds, and the soup base has some fresh aroma of kelp, which has also won the recognition of many diners. Liu Yi's bowl of duck blood vermicelli soup has only one choice, which comes with duck blood, tofu fruit, duck liver, duck intestines and duck gizzard by default, and finally sprinkled with coriander to enhance the flavor. However, the saltiness of the duck soup is neutralized by the saltiness of the kelp shreds, and the soup base itself has enough saltiness, and the marinated duck liver also has its own salty taste, but it is slightly bitter in the aftertaste, and the diners with a light taste are easy to get greasy after eating for a long time. However, the duck intestines are quite crispy, and the duck gizzards are more chewy. Liu Yi's bowl of duck blood vermicelli soup can be added with duck offal and vermicelli, and there is no pot to sell now.

There is only one duck blood vermicelli soup, and there is no rich ingredient matching, so this duck blood vermicelli soup seems a little monotonous. Other dishes in the store, such as chicken soup dumplings, are rich and abundant, but the filling skin is too thick, the meat filling is full, and it is easy to get greasy. Liu's bowl of soup dumplings is full of filling, which is naturally a good choice for meat lovers, but when such soup dumplings meet duck blood vermicelli soup, the taste buds are mixed with too much saltiness and sweetness, and the feeling of freshness is missing. In addition, Liu's bowl is served with self-picked pickles such as radish and cowpea, which is recommended to be eaten when ordering other dishes, and if it is paired with duck blood vermicelli soup, it will increase the saltiness of the dish.

However, Liu Yiwan's other dishes are not too good, except for duck blood vermicelli soup, which can be eaten as an ordinary meal.
