We will be in Atlanta for, yes, a convention, in late March. Totally dependent on MARTA . Hotel is, of course, downtown. Am not looking for Underground food courts, The Varsity, expense account steakhouses, etc., etc. Have a Southern grandma so don't need requisite chitlin stops. Have also recently overdosed on barbecue. Willing to travel far on MARTA if chow is chowhound worthy, but not too eager to walk about at night too far from MARTA stop. Downtown recs that are walkable would be appreciated too. Budget is not in the general $$$ Buckhead range, but can go for a splurge now and then. Would appreciate any help. TIA.
