I had one of those the other day. I marinated only for about 12 hous though with Red Wine, Italian Dressing, Montreal Steak Seasoning, and Garlic Salt. Damn it was awesome. Nice, tender, and bloody!
In about a week or so I am going to order myself about 6 to 8 lb of Prime Rib to make up when I have a little party over at my place.
Last thing I ate was scrambled eggs and fried ham.
