Barros Luco is a simple Chilean sandwich that usually consists of thin slices of grilled beef steak topped with cheese (usually havarti) and served inside various buns and bread rolls. It got its unique name after the Chilean president Ramón Barros Luco, who was a great admirer of this satisfying sandwich.

Even though it is unclear whether it originated in the restaurant of the Chilean National Congress or the Confitería Torres, to this day Barros Luco remains as one of the most popular sandwich varieties in Chile. It is always served hot and can be found on the menus of many Chilean restaurants.
