Best areas in Atlanta? Social sports?

I am moving to Atlanta this Fall, where are the best areas to live for pickup in the north/northeast? I'll be working in the northeast suburbs but am looking for areas that have easy access to bars, restaurants, and meeting women in their 20's. I'm 30 with a good salary, so I'd like a good quality of life & have a place I'm happy to come home to. I know no one & will be starting from scratch.

Also, what are the best co-ed social sport clubs (ie kickball)?
