Founded in 1763, with an exquisitely simple boiserie interior dating to the early 1800s, this one-room cafe takes its name from its signature drink, a potent combination of chocolate, coffee and cream. Fuelling the likes of Dumas, Puccini, Nietzsche and Calvino, along with Savoy royalty and Turin's workers, the price didn't rise for a century to ensure no one missed out.

　　Zabaione, an eggy, boozy concoction, is also a speciality, plus there's either cake or cocktails for afternoon sustenance.
