This is an elegant italian restaurant with an outside patio in the summer. It is in the Palais Esterhazy which is a nice setting and is central (not far from the Graben).
They have everything from simple Pizza (around 10 Euros) to Vitello tonnato (10,90 Euros) which is a delicious starter with sliced veal covered with a tuna sauce.
