Howdy! Here in Northern California, there are two mainsteam supermarkets (Lucky's and SaveMart) that carry what they call "100% Guaranteed Premium Master Cut Aged Tender Beef." Unfortunately, I have been unable to find ANY usefull information on their brand of meat, grade, processing practice, whether it is great, horrible or about the same or better than Safeway's Rancher's Reserve. Any information you can pass on will be most appreciated. Thanks!
