I don't know why anyone wouldn't like CME...it's my favorite store and I've been to all of the big stores in Nashville and LA (which do have stores I love, don't get me wrong).
They let kids play guitars they could never own, they have soundproof gear testing rooms, they have massive mass produced, boutique, AND vintage selection, and it's very home-y with couches and magazines and all of that.
And yes, they are the best PRS dealer in Illinois, as far as I'm concerned. I'm parked right between Chicago and St. Louis distance wise and I'll always go to Chicago and go to CME.
