In my opinion, each city has its own unique food culture and special catering. Some cities may need more time to explore and find, but this does not mean that they are gourmet 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 from different angles. The following cities can be regarded 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 the flavor of 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. Nova Diliz: There are almost no 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 is not doing well in attracting domestic and foreign tourists.

6. Kolkata (India): Although India has a rich food culture, it seems that Kolkata has failed to attract enough investment and attention in this respect.

7. Ljubljana (Slovenia): This small town has some interesting food, but it is not satisfactory in attracting the world's attention.

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