We spent some intense days, full of stimulating relationships and discussions, which ended in an unforgettable guided tour with Livio Barbagallo in the footsteps of Rossini and especially of the mythical impresario Barbaia, a real businessman who knew how to do business and who sent to Vienna the legendary singers that Hegel 1824 listened to and admired. He invented a very good coffee that can still be tasted at Gambrinus!
