Lao Xiang Lou was founded in 1999 and belongs to one of the earliest Hunan restaurants in Guangzhou. Lao Xiang Lou has been rated as a famous restaurant in Guangdong by the Guangdong Food Association for many times, a famous Chinese restaurant by the Hong Kong Food Promotion Association, and also recommended as "the most distinctive Hunan restaurant in Guangzhou" in the "Weekend Pictorial". In 2015, Lao Xianglou upgraded its brand and transformed into a theme restaurant brand specializing in fish heads, "Youyouji Sauerkraut Fish". Laoxianglou currently has 23 branches in Guangzhou, and the business model has two types: direct sales and franchises, and direct stores are more recommended. The signature fish head is selected from the big fish of the Dongjiang Reservoir in Hunan, with a growth period of two to three years, and the net weight of the fish head is more than three catties. The freshly caught fish will be slaughtered that night and delivered to stores in Guangzhou early the next morning. The cooking oil is pure rapeseed oil, which is the standard for Hunan people to eat bowl vegetables. In addition, sauerkraut, capers, and spicy sauce are all homemade from an exclusive secret recipe. In Laoxiang Building, there are more than three ways to make the signature fish head, such as sweet and sour tomato lemon fish head, spicy green pepper perilla fish head, sour pickled pepper fish head, etc., which can be selected according to personal preference. Laoxiang Building has a perfect management system, and the pastoral distribution center, local vegetable production base, and vocational training center all provide guarantee for stable production. Although the decoration features of Lao Xiang Building are different due to different branches, it still has a faint Hunan flavor on the whole, and at the same time, urban elements are added to adapt to the majority of young consumers, and the service level is also good overall. In some online promotions, it is said that the sauerkraut fish is only produced in fish dishes, but in fact, it also has a variety of dishes to choose from. In addition, Laoxiang Building is mostly opened in downtown areas or office building areas, and it is cost-effective, so it has become a canteen for many white-collar workers.
