I'm traveling to Atlanta for the first time this coming weekend. I will have one night to find dinner on my own, somewhere in the vicinity of the hotel where I'll be staying (the Hilton at 255 Courtland St., NE). I won't have a car, but I gather the hotel is 2 blocks from the MARTA. I'd love any suggestions for an excellent dinner, somewhat on the "splurge" end of the spectrum. Is there any place nearby that serves something that you still think about with pleasure days later? Despite the "nom de Chowhound", sushi is not a requirement! Thanks in advance.
