First of all, food is a subjective concept, so everyone's evaluation and preference of food may be different.

For example, some people may find a city's specialty cuisine to be delicious, while others may find the food there mediocre.

Therefore, evaluating a city’s gastronomic quality requires taking into account a variety of perspectives and evaluation criteria.

Secondly, even if a city's food culture is relatively lacking or lacks popularity, you can still find some local food worth tasting.

For example, some niche local specialties or traditional home-cooked dishes may not be so well-known, but they may bring unexpected surprises.

Finally, every city has its own unique food culture and historical background.

Some cities may not have many well-known restaurants or food brands, but they have rich local specialties and unique food cultures.

For example, some remote areas or small towns may not have large chain restaurants, but they have unique local cuisine and traditional food culture.

Therefore, many factors need to be considered when evaluating a city’s gastronomy.

Different cities may have different food characteristics and advantages, and we cannot easily conclude which city is a food desert.
