The opulent colonial-style house on the grounds of the Mandarin Oriental Hotel harkens back to the roaring 1930s Shanghai with dark woods, low lights, and splashes of color accenting the space. The unlimited dim sum buffet Tuesday to Friday fills the house during lunchtime, and bamboo baskets of the bite-size treats arrive in unending fashion until everyone is good and full. Weekends are popular with hungry families looking for a weekend brunch spot. But it’s the perfect Peking duck wrapped in paper-thin pancakes that really steals the show, and it would be a shame to leave without ordering the signature dish.
