Thanks to all the recommendations. I ended stopping at Fresh Market, as it reminded me of a specialty store I would frequent where I lived before. They didn't offer any dry aged that I saw and I was pressed for time, else I would have very likely visited the place up in Fairfax. We'll see how these bad boys cook on the grill. +rep to those that have replied thus far, assuming the forum allows me to do that many.

Thanks again!
