Five brothers first opened the bar "Onis" in 1976 after migrating to Madrid in the early 1970's from a village in the North of Spain. The possibility of making money brought them into the hospitality business in the big city. Since the opening of the "Onis" forty years ago, they have worked together almost every single day.
