Crabbing, I think Bingo Loco gave you some good suggestions although I've only been to about half of the places mentioned. I live a little northwest of the city so I'm more familiar with restaurants in Vinings, Smyrna, Marietta and the outlying areas.

If you ever find yourself in this area:

La Paz is great for Mexican. Nice staff, good food and good service.
Uncle Wong's is nice for Chinese or Thai.
Blue Moon Pizza has some delicious pizza, wings, salads and such.

Hope our suggestions have helped.
