Good food near the Georgia World Congress Center in Atlanta?

I’ll be attending a conference in a couple of weeks at the GWCC, and staying at the Hyatt Regency. Any suggestions for nearby good places for dinner (either walking distance, or a short cab ride away)? Doesn’t have to be fancy – non-chains preferred. No particular preferences – just good food.

TIA, CV
