The story
The first restaurant was opened in 1983 near Pontificia Universidad Javeriana by Pablo Emilio Bueno and Guillermo Calderón. In 2001, El Corral opened its first Corral Gourmet restaurant, offering not only hamburgers with different gourmet toppings such as aged cheeses, Argentinian sausage, stir-fry vegetables and different bread options and a range of liquors in its bar.
In 2014, Grupo Nutresa bought El Corral and Beer Station from previous owners Grupo Va!.
