This soup is called Ajiaco. To be exact, this particular one is called Ajiaco Santafereño, implying that it followed the recipe in Santa Fe region in Colombia, I assume.
According to Google, Ajiaco is a popular dish found in Colombia, Peru, and Cuba, and the origin of the dish is still unclear.
As seen, the soup contains chicken, potato, corn and avocado. Although the list is not enough to give an idea about the taste, it was like a smooth and medium-heavy chicken soup.
