Four Cats restaurant has been in business for 117 years since 1897. Picasso, Dali, Milo, Gaudi... these masters often linger here when they are not known. In 1900, 19-year-old Picasso held his first solo exhibition here. It was the center of the modernist movement in the late 19th century, and Picasso made posters for four cats, which later became the cover of today's restaurant menu.
