There are not many Hunan restaurants with more than 15 years of qualifications in Shanghai, and Guyi is one of them. In 2001, Guyi's first restaurant, Fumin Restaurant, opened, and became a well-known Internet celebrity Hunan restaurant at that time. It has been reported by many media such as Shanghai Lifestyle Channel, Japan NHK, Shanghai Education Channel, etc. It has won awards such as "CITY WEENKEND's Best Specialty Restaurant in China" in 2012-2013, "CITY WEENKEND's Best Spicy Chinese Cuisine" in 2015, and "CITY WEENKEND's Outstanding Spicy Chinese Cuisine" in 2016-2017. The ancient Hunan restaurant enjoys the status of the first Hunan restaurant in the hearts of the old Shanghainese, and has maintained a good popularity since its opening.

Guyi mainly produces the representative cuisine of Hunan in the Xiangjiang River basin (centered on Changsha, Hengyang and Xiangtan). In terms of taste, it has been improved, using low-fat and healthy camellia seed oil, and using its unique fragrance to match the flavor of rich chili peppers, breaking through the limitations of traditional Hunan cuisine. Guyi's gold medal dishes are also indispensable for fish heads. The fresh and spicy sauce pepper is used, which is not too heavy, and it has an extra clam in the dishes of similar stores, which gives it more umami. Bamboo bullfrog legs are also a feature, fresh bullfrogs are placed in bamboo tubes and plated, using ancient homemade chopped peppers, the frog leg meat is firm and delicious, and it also contains the fragrance of bamboo. A simple dish of salted egg yolk fried prawns has stable strength, and the fresh prawns are wrapped in a layer of glutinous salted egg yolk, which is salty and fragrant and not greasy, catering to the taste of the public. The pork knuckles marinated and then fried with dried chili peppers are fat but not greasy, and they are also one of the popular dishes in the store. In addition, stir-fried Dong'an chicken, stir-fried pork with chili peppers, stir-fried chicken offal with sour peppers, and stir-fried eel slices are also indispensable. However, the improved light taste is not very authentic, so the ranking on the list is relatively delayed. It is recommended for diners who don't know how to eat spicy food but also want to taste the flavor of Hunan cuisine.

Compared with the other three Guyi branches opened in the mall, the Guyi Fumin store, which is an independent store, was the first to open and is also the most famous. It is located next to Jing'an Temple, so many foreigners choose to dine here. The strength of the dishes of Guyi Restaurant has always been at a medium level, and there has been no obvious improvement and improvement. The portion of the dish is small, the cost performance is not high, and the serving speed is relatively slow. With the rise of high-quality Hunan restaurants in Shanghai, the status of ancient Internet celebrity Hunan restaurants is gradually declining. The interior of the restaurant is clean and bright, with a simple and elegant style, and the distance between adjacent tables is narrow, and the hotel is slightly noisy when there are many people. There are many non-meal charging items in the restaurant and the unit price is high, pre-dinner snacks need 4 yuan a stack, towels 3 yuan, tea table fee 5 yuan, you can tell the waiter in advance whether you need towels and other items, so as not to know after checkout.
