Can't say it's the city, every city in China still has a good place, personally I think it's some of the commercialization of the place led to the food desert, I think the Shanghai Xujiahui shopping district there is such a problem. I think the Xujiahui business district in Shanghai has such a problem. We can describe the situation of "food desert" in the Xujiahui business district in the following aspects:

1. Lack of local specialties: The catering industry in the Xujiahui business district is mainly dominated by international brands and fast-food chains, and it is difficult to find local specialties. Even some local food and beverage brands tend to pay less attention to the promotion of specialties and instead focus on standardized and scaled services.

2. Lack of innovation and diversity: Most of the food and beverage venues in the Xujiahui business district are chain brands, which tend to lack innovation and diversity. In addition to some fast food brands, it is difficult to find new and creative dining places, making people feel a little monotonous and boring.

3. Uneven quality of food: In the Xujiahui business district, due to insufficient competition in the market, the quality of food varies, and even the food quality of some chain restaurants is hardly satisfactory.

4. High price and low cost performance: Dining establishments in the Xujiahui business district tend to have high prices but low cost performance. Many fast food restaurants are more expensive compared to other areas, and the taste and quality of the meals are not as good as similar stores in other areas.

For example, there is a famous Taiwanese restaurant chain called Din Tai Fung in the Xujiahui business district. Although this restaurant is very famous in Taiwan, in the Xujiahui district, the price of its food is high, and the taste and quality are not satisfactory. In contrast, restaurants in other areas may have more local specialties and more affordable prices.

The Xujiahui district is a "food desert", mainly due to the impact of commercialization, resulting in a lack of local characteristics and innovation in the restaurant industry, as well as uneven quality and value for money.
