In my opinion, each city has its own unique food culture and special catering, and some cities may need to spend more time exploring and searching, but this does not mean that they are food deserts. In addition, the definition of food varies from person to person. Some people think that rich food choices are important, while others may pay more attention to the quality and taste of ingredients. Therefore, when answering the question of urban gourmet desert, we need to think and analyze it from different angles. The following cities may be considered as food deserts only in terms of food types, tastes and quality:

1. Lusaka (Zambia): This city does not have very famous local dishes, but mainly provides flavors from other countries.

2. Ashgabat (Turkmenistan): Because it is located in the center of the desert, the food here is very monotonous, mainly meat and horse milk.

3. Novadilis, Portugal: There are few restaurants in this city except the city center. Even in the city center, there are only some simple small restaurants.

4. Dakar (Senegal): The main food in this city is fish and rice, but the choice of restaurants is much less than that in other cities.

5. Montevideo (Uruguay): Although Uruguay is rich in culture, the city has not done a good job in attracting domestic and foreign tourists.

6. Kolkata (India): Although India is rich in food culture, it seems that Kolkata has not attracted enough investment and attention in this respect.

7. Ljubljana (Slovenia): There are some interesting foods in this small city, but it is not satisfactory in attracting world attention.

It should be pointed out that the cities mentioned above do not necessarily represent the food culture of the whole country, but only describe the cities themselves. At the same time, these cities may also have blind spots in food culture. If you are still curious about the food culture of these cities, you can also travel to these cities to experience and explore the local food culture for yourself.
