The reason for this is the following：

1. Shanghai's delicious food is hidden in the alley, which is not easy to find and the price is not cheap. Without the help of local people, it is difficult for newcomers to Shanghai to find affordable and delicious fast food. Moreover, the quality of take-away food in Shanghai is not high, and many stores do it casually, with no characteristics and standards.

Shanghai's local dishes are not popular. Many people think that the local dishes in Shanghai are too sweet, too greasy and too salty, and there is no refreshing and delicious feeling. Shanghai's traditional snacks, such as steamed buns, braised pork and fried buns, have also been criticized for their lack of exquisiteness and innovation. Time-honored restaurants in Shanghai have also been accused of being unpalatable and expensive.

Shanghai lacks the special food and flavor of other places. Many people think that Shanghai is an international metropolis and there should be all kinds of delicious food for people to choose from. However, Shanghai's food culture has not well integrated and absorbed the characteristics and advantages of other places. For example, Shanghai has no representative restaurants with Shandong cuisine, Sichuan cuisine, Cantonese cuisine and other major cuisines like Beijing. There are no hot pot, skewers, maocai and other snacks and supper like Chengdu. Shanghai is not as rich in fresh seafood and morning tea as Guangzhou.

Shanghai cuisine has not formed its own characteristics and brand. Shanghai cuisine does not highlight its own regional characteristics and cultural heritage, but imitates and draws lessons from the cuisines and styles of other places. For example, the local food in Shanghai is considered as a variety of Huaiyang cuisine, and the snacks in Shanghai are considered as replicas of Nanjing, Suzhou and Wuxi. Shanghai cuisine has not formed its own brand and logo, so it is difficult for people to recognize it at a glance.

Shanghai cuisine has failed to keep up with the changes and demands of the times. There is no innovation and progress in Shanghai's cuisine, but it stays in the old routine and old taste of the past. For example, Shanghai's local cuisine is considered suitable for the elderly and conservatives, and there are no dishes that attract young people and fashionistas. Snacks in Shanghai are regarded as unbalanced and unhealthy foods, which do not conform to modern people's health awareness and eating habits? .

Shanghai cuisine has not been sufficiently promoted and publicized. Shanghai's delicious food has not been effectively displayed and spread to the outside world, but has been buried in the bustling and noisy urban life. For example, Shanghai's local cuisine is considered to be known and liked only by local people, but it will not impress foreigners and foreigners. In Shanghai, snacks are considered to be sold only in street stalls and small shops, not in high-end restaurants and shopping malls.

The reason why Shanghai has become such a gourmet desert is also very complicated. I made a brief analysis:

1 Shanghai's historical position has affected its food development. As the most important commercial and financial center in China's modern history, Shanghai has attracted immigrants and businessmen from all over the country and the world. These people bring a variety of eating habits and tastes, which makes Shanghai's food diverse and mixed. Shanghai has not formed its own independent and complete cuisine, but has borrowed and integrated the cuisines from other places, such as Huaiyang cuisine, Sichuan cuisine, Cantonese cuisine and Western cuisine. Although this kind of food enriches Shanghai people's dietary choices, it also makes Shanghai's food lack characteristics and recognition, and it is difficult to form its own brand and influence.

Shanghai's cultural atmosphere affects its food quality. As the largest city in China, Shanghai has a fast pace of life and great pressure. All these have affected the demand and attitude of Shanghai people towards food, making them pay more attention to the convenience and benefits of food, rather than the delicacy and innovation of food. Therefore, Shanghai's cuisine is often dominated by fast food, snacks and take-away, rather than high-end restaurants and large restaurants. Although this kind of food meets the basic needs of Shanghai people, it also makes the food in Shanghai lack quality and standards, and it is difficult to achieve high-level aesthetics and enjoyment.

Shanghai's political environment has influenced its food communication. As one of the most important political and economic centers in China, Shanghai has experienced many political changes and social unrest. All these have affected the inheritance and development of Shanghai cuisine, resulting in some traditional cooking skills and culture being interrupted or forgotten, and some excellent cooking talents being forced to leave or change careers. Therefore, it is difficult for Shanghai cuisine to form a stable and sustainable development system, and it is also difficult to show and promote its own food culture and value to the outside world.
