Despite the name, no gambling — this is the city's leading contemporary art exhibition space, in a 19th-century building that was actually a private bourgeois club called the Casino. Franz Liszt gave a recital here in 1886. Today the programme runs strongly conceptual and experimental, with five or six major exhibitions a year.
Closed Tuesdays. The ground-floor café-bar Ca(fé)sino spills onto a courtyard terrace in summer.
