Originally called the Sheep Fold because of its use as quarters for the herd of sheep that kept the grass clipped on the meadow across the Drive, this building was converted into a restaurant in the 1930s. After expansion and remodelling twenty years later, it became what it remains to this day: one of the most successful restaurants anywhere in the United States. Its new incarnation was the inspiration of the late Warner LeRoy, who added a highly theatrical dining room that could be the setting for a Viennese operetta. As he described it, he intended to make it âœa kind of living theater in which the diners are the most important members of the cast.â The glass walls of the dining room overlook a topiary-filled outdoor dining area with glittering lights shining from the trunks and branches of the surrounding trees. Eating there is like celebrating Christmas all year round.
