All in all, the Cavalieri has what is widely considered to be the world's best hotel art collection. It also happens to have the best restaurant in Rome — rooftop La Pergola, under the reign of German star chef Heinz Beck, and one of just six restaurants in Italy to boast the Michelin Guide's top accolade of three stars.
When the Cavalieri opened in Rome in 1964, the Dolce Vita was still in full swing, and for Italians still emerging from wartime austerity the Hilton name carried all the right connotations of American cocktail-set panache and elegance. But that was before Hilton Worldwide gathered 3,500 hotels in some 81 nations.
