Of noble proportions and of a style that recalls state dining rooms in English country houses of the 18th century, the Dining Room was an appropriate setting for the formal dinners that Mr. Frick hosted, at a rate of two per week, from October through May. Lining the walls are 18th-century British paintings, a customary choice for the dining room of a grand residence. Because the furniture in this room was to be used, it was modern. Mr. Frick’s interior designer, Sir Charles Allom, based his designs on English models of the 18th century. From the basement kitchen, food was sent up via a dumbwaiter to the adjoining Butler’s Pantry.
