Make your reservations ahead of time if you want to eat in a place where you can feel like a star and dine like royalty.   Mahogany and teak, walls festooned with with movie star caricatures, and a brilliant chandelier make the Derby an elegant dining experience.   We enjoyed a great pianist/singer and an outstanding meal.   If you time your leisurely dinner just right you can be out in time to see Sorcery in the Sky Fireworks.
