Choice grade beef has less marbling than Prime, but is still of very high quality. This is the most popular grade of beef because it contains sufficient marbling for taste and tenderness, while costing less than Prime, with Choice cuts being juicy enough to make that dinner of yours still delicious and amazing. Beef filet mignon roast, also known as a beef tenderloin is a very exquisite cut of meat. The tenderloin is located in the back half of the steer, and is the least worked piece of meat and it is not a weight-bearing portion of the steer, which results in less connective tissue, and more leaner and tender cut of meat. This makes the tenderloin the most expensive of all cuts of meat.
