Over the years, I've purchased steaks at Siesel's (before and after Cohns took over), Iowa Farms, Tip Top, Harvest Ranch, Costco and even Valley Farms Market in Spring Valley. All sell top quality, prime beefsteak and I've had varying degrees of success at each place.
I've now purchase steaks three times at the butcher shop which is a part of Cowboy Star Restaurant downtown on 10th Ave., and I've got to say, the quality and consistency of their steaks is a distinct cut above all the others. I got a well-trimmed, bone-in ribeye that was the best I've ever tasted. Filet Mignons recently had great 'structure' (not flabby or rubbery) and taste. The wagyu hanger steak was also very special.
They carry a small selection of other non-beef items, I remember seeing some chicken, but for special occasion steaks to prepare at home, I believe they're the best in town right now.
