Commanding breathtaking views atop the Island Shangri-La, Restaurant Petrus scales the upper Hong Kong heights of prestige, formality, and price. This is one of the city’s few flagship hotel restaurants that has not attempted to reinvent itself as fusion—sometimes traditional French haute cuisine is the way to go. Likewise, the design of the place is in the old-school restaurant-as-ballroom mode. The kitchen has a particularly good way with foie gras, and the wine list is memorable, boasting more than 1,500 vintages from some of the world’s best wineries. The dress here is business casual—no jeans, sandals, or short-sleeved shirts for men.
