Dalongyi is also an authentic Chengdu hot pot, although its development momentum is not as good as Haidilao and Xiaolongkan, but every time it arrives in a new city, it will still cause a queue boom. At present, there are more than 180 stores around the world, including 3 in Hangzhou.

Da Longyi and Xiao Longkan, as representatives of "phenomenal catering" in the past two years, are inevitably compared with each other. At this time, the number of floating populations in various parts of the country has increased significantly, and they have a certain adaptability to spiciness, so Xiaolongkan and Dalongyi are not divided according to the region in terms of taste, and the taste of all parts of the country is basically the same, but the spiciness is slightly different. The difference is that the taste of the bottom of the Xiaolongkan pot is relatively balanced, while the spicy taste of Dalongyi is always more prominent. 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 the spiciness of Erjingtiao is not as good as Chaotian pepper and Mantianxing, but the color is red and bright, and the pepper fragrance is strong, which is also a reason why many customers feel that Dalongyi's spicy taste is stronger. Judging from the actual feedback, although the taste of Da Longyi is authentic, not every customer can accept it, and the spiciness of the bottom of the pot in Hangzhou has been reduced, and it is still too spicy for many local diners, which may be more suitable for customers in Sichuan and Chongqing or friends who are not spicy.

Pig Paradise is a special dish of Da Longyi, which is relatively rare in other hot pot restaurants in Hangzhou. Pig Heaven is a circle of meat on the palate of the pig's mouth, the shape is ladder-shaped, the color is pink, it is also called the pig tooth terrier, the pig ladder in the Sichuan-Chongqing region, the taste of the pig heaven after scalding is similar to the yellow throat, but it is firmer than the yellow throat, and it is also more chewy. Fragrant tofu is also rare, although the name is "tofu", but it is actually made of chicken, starch, seasonings and other materials, the spiral two fragrant tofu are connected end to end, after the pot absorbs water and swells, diners who like the texture of the chewy can eat immediately after blanching, if you prefer smooth and soft, you can cook in the pot for a long time and then enjoy. Beef and mutton are not recommended to be ordered, and some meat rolls are separated from the lean layer with a light fat layer, and the quality of the ingredients is very average.

Da Longyi's flavor dish is as simple as Xiao Longkan, with only two types: oil saucer and dry dish, the oil dish is sesame oil with garlic, chopped green onion and coriander, and the dry dish is composed of chili powder, Sichuan pepper powder, fried white sesame seeds and peanuts. There is no spice buffet in the store, and there are no side dishes or fruits to serve. If you feel that the bottom of the pot is too spicy, it is recommended to order an oil dish, which can not only enhance the flavor of the pan, but also have a certain effect on reducing the temperature and spiciness of the food. When you are hearty, you can also have a bottle of frozen Weiyi soybean milk, which also cools down and relieves spiciness.

In 2016, a 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.

Several stores in Dalongyi have a strong Bashu atmosphere, with red lanterns, wooden tables and chairs, hollow screens, and Sichuan opera masks well matched, and the whole store gives people a bright and spacious appearance. However, the exhaust of the store is not smooth enough, and there will be an obvious feeling of suffocation during the meal, and there will be a large smell on the body after eating. The store service staff lacks a sense of active service, and the apron needs to be requested by the customer himself, and the response speed will be greatly reduced during peak hours.
