Another specialty made famous at Delmonico's, Delmonico steak stands for different cuts around the United States. In some parts of the country this tender, flavorful steak is a boneless beef cut from the short loin. Depending on the region, butcher and so on, it's also referred to as a New York steak. In other sections of the United States the Delmonico steak is a boneless rib-eye steak, also called a Spencer steak. There's also a third description in some areasa steak cut from the sirloin, which is right next to the short loin. All Delmonico steaks can be broiled, grilled or fried.
