Chef Michael McMullen has reenergized this upscale dining room with a new menu. Favorites include spicy shrimp and grits, maple horseradish mustard crusted baby rack of lamb, and cedar plank roasted sea bass. Service is among the best in town. The highlight of the dining room is the array of celebrity caricatures that cover the walls. They were done by Jack Rosen, father of hotelier Harris Rosen (hence the name of the restaurant), when he was employed by the Waldorf Astoria in New York.
