Question: what is the difference between prime rib and delmonico steak?
Answer: Ultimately, the Delmonico steak is as much myth as it is a specific cut of steak. If it's a thick, good quality steak from the rib or short loin, you could call it a Delmonico. Delmonico's Restaurant is still in business, and on their menu, the Delmonico steak is a boneless ribeye.
