My native city is Cúcuta. It is smaller than Cali, but bigger than Pamplona. Cúcuta is very hot, I think is the hottest city between Cali and Pamplona.
Now, let's talk about the most important: The food. Well, I have eaten the tipical food of those cities and in my opinion the food in Cúcuta is the most delicious. Although the food in Cali and Bucaramanga is very delicious too.
