I'm afraid I'm not much help on MSP, Marie, although a friend who goes there often says there are surprisingly good eateries in the Mall of America. (I'd steer well clear of that place myself, but in fairness, passing this along.)
I wonder if the Black Sea Restaurant is from Georgia, not the one with Atlanta in it but the one with Tbilisi in it. We went to a Georgian restaurant in Seattle years ago, and it was awesome. Of course, this speculation isn't telling you what the Minneapolis Black Sea is like, but if it were me, I'd check into that.
