No, but I've been meaning to try it out. It was recommended to us by Ben Michael from Ben Michael's on Rio Grande. Apparently the Cafe Green folks are friends of his or used to work for him. Anyway, I like Ben and his food so my guess is Cafe Green is definitely worth a try.
I know they recently got a glowing review in the Alibi or the iQ, but the one and only time we went for breakfast (maybe a year ago?), it was distinctly Denny's-esque (which, for the record, is not a good thing).
