Da Long Yi is a Sichuan-style hot pot from Chengdu, with more than 180 stores in China, and has been awarded many honors such as "Top 50 Chinese Hot Pot Brands", "Top 10 Chengdu Hot Pot" and "Sichuan Catering Gold Medal Store".

Like Yuwei Xiaoyu hot pot, Da Longyi did not improve the taste of the bottom of the pot in order to cater to the taste of the locals, and only partially reduced the spiciness and numbness, so the taste in Suzhou is not much different from that in Chengdu. In addition to Pixian bean paste, a variety of spices, a lot of Erjingtiao chili peppers are added to the bottom of Dalongyi's red soup pot, although its spiciness, it is not as hot as Chaotian pepper and full of stars, but the color is red and bright, and the pepper fragrance is strong, which is also a reason why many customers feel that Dalongyi chokes on the spicy taste. For Suzhou diners, the pure taste of the red soup pot may be too heavy, it is recommended to order a slightly spicy one, if you want to relieve the spicy taste, you can also choose two types of pot bottoms: mandarin duck soup or tomato mandarin duck.

In terms of flavor dishes, Da Long Yi has not been improved. The oil dish is canned sesame oil, one can per person, and the rest of the ingredients are only chopped green onions, garlic paste, coriander and oyster sauce; If you order a spicy dry dish, it's a plate of chili noodles dipping sauce. If you can't eat spicy food, it is recommended to order an oil dish, which can not only enhance the flavor, but also have a certain effect on reducing the temperature and spiciness of the food.

There are three types of hairy tripe served by Dalongyi: chilled hairy tripe, grassland mille-feuille tripe and green hairy tripe, and the three hairy tripe sources and tastes are slightly different. Mille-feuille belly and hairy belly both belong to the stomach of the cow, the cow is a ruminant, a total of four stomachs, rumen, net stomach, valve stomach and wrinkled stomach, the four stomachs produce different ingredients, the taste is not the same. Among them, the most common hairy belly comes from the rumen, which has the most elastic taste; The money belly, which is often used as a marinade, is part of the net stomach, and the taste is crispier and thicker than that of the hairy belly; Mille-feuille tripe, also known as beef shutters, comes from the petal stomach, and like hairy tripe, it is often used as a hot pot hot sauce; The fourth wrinkle is generally used for stewing or boiling. Da Longyi's iced hairy belly is rumen hairy belly, the taste is elastic and tough, and the grassland belly is made of beef mille-feuille belly, which is long in shape and yellowish in color. These two kinds of hairy tripe belong to fresh hairy tripe, which is a fresh hairy tripe that is cut off from the stomach and washes the mucus and scrapes off the thick membrane, which is normally gray or yellow-black, while the third kind of green hairy tripe is cut and uses proteolytic enzymes to hydrolyze and tender the protein in the hairy belly, and the taste is more crisp and tender. Unfortunately, the Da Long Yi big knife belly, which has been well received in other cities, has disappeared in Suzhou.

Tongwei fish skin is a specialty dish of Da Long Yi, and only Da Long Yi is available in Suzhou hot pot restaurants. According to the store, Tongwei fish skin is made from Hainan crucian carp, which is processed by the Chengdu head office before being sent to the Suzhou branch. The fish skin on the table is large and neat, the texture is soft, and it can be eaten by blanching it in the pot for 6-7 seconds with chopsticks, and it is smooth and crispy in the mouth, without any fishy smell. Sichuan wide flour is often called coconut flour and hot pot powder in Sichuan and Chongqing, mainly made of sweet potatoes, the color is dark gray, and it becomes crystal clear and transparent after being blanched, and the taste is soft and glutinous and elastic.

In 2016, a Dalongyi branch in Wenzhou was exposed to the use of old oil, after which Dalongyi strengthened the supervision of franchisees, launched the flight inspection mechanism, and inspected the franchise stores from time to time within a year, and changed the hot pot base from oil packaging to oil mixing, after the bottom of the pot is used, the waste oil recycling company recognized by local government departments will process the hot pot oil, which will be more guaranteed than before.

Da Longyi currently has 2 branches in Suzhou, the decoration style of the 2 stores is unified, the dining area is hung with red lanterns, the wall is painted with Sichuan opera masks, the Bashu atmosphere is strong, and the whole store is bright and spacious. Dalongyi's service is decent, the waiter lacks the sense of active service, and only relies on the customer's own needs, and the response speed will be greatly reduced during peak periods.
