Excellent steakhouse. Every time I visit Las Vegas I make sure to get a comp for Delmonico. It consistently remains a solid restaurant. One of my favorite restaurants overall.
Service is great.
Food is amazing. Trumpets sounded when I took my first bite into the "Bone-In Ribeye."
I would highly recommend that you discuss with your server the definition of medium rare and medium. I know one time a friend said it was undercooked for medium rare, but honestly it was fine. He had a different definition for medium rare based on past experiences with "other steakhouses" (but I am not sure I would refer to them as real steakhouses).
