A New York Strip steak (also known as shell steak, Kansas City Strip, etc.) is the same cut of meat (short loin) that is the larger, top part of a T-Bone steak. The big difference, of course, is the "strip" is boneless.

A New York strip steak is not the same as a sirloin cut. They do however both come from the loin area of the cow. The difference is that the strip steak comes from a more tender part of the loin.

Cooking a beef strip loin steak on the grill is a great way. It is easy to overcook if not watched carefully.
