The Viennese café is a typical institution of Vienna that still plays an important role in Viennese culture and tradition. Unlike some other café traditions around the world, it is completely normal for a customer to linger alone for hours and study the omnipresent newspaper. Along with coffee, the waiter will serve an obligatory glass of cold tap water and during a long stay will often bring additional water unrequested, with the idea being that you are a guest who should feel welcomed and not pressured to leave.
