Prime Rib, Tied & Bone InElevate any occasion with our Prime Rib. Tied and Boneless, the flavor will blow you away! And, there's TONS more value as you're only paying for the beef not the ribs too! How do you know what weight to buy? Take the number of people you're serving and then decide how it's being served. In general, an American cut steak is around 1" 1 pound or, if you're serving it shaved and your group isn't big into beef, plan on at least a half pound per person.
