It was very good but also so rich that it was hard to eat more than a small piece. This may be sacrilege, but when it comes to rib eye and rib roast, I think I prefer choice over prime for a dinner.
The Mariano's Fresh Market in the West Loop (Chicago) carries dry aged beef and prime non-aged beef. I still buy it from the local butcher because he is substantially less expensive, but its nice to have a choice. Dominick's (Safeway) meat selection and quality blows.
