The engaged couple, who recently obtained a marriage license in advance of their planned nuptials in Italy, dined at the Grand Hotel Villa d'Este at Cernobbio on Aug. 7 near Clooney's Lake Como home.
"George kissed Amal and she gave him a neck massage," an observer says. "They looked very much in love. After dinner the two took a stroll through the gardens arm-in-arm."
Clooney, 53, and Alamuddin, 36, also went for a boat ride before leaving town on a private jet.
In July, Clooney told Variety of his lawyer fiancée, "I'm marrying up."
