Go to shooters on Milgen rd here's their website:

Go to the museums. I've never been there, but I hear they are GREAT.
UNLESS YOU WANT TO GET ROBBED/KILLED/SODOMIZED , STAY THE HECK OFF OF THE SOUTH END, AT LEAST AT NIGHT!!!!
I was a beat cop there a decade ago (oh, where does the time go???) and I still have friends there on the job. It's OK near the interstate during the day, especially Ranger Joe's http://www.rangerjoe.com/ and you should go there, too. But Having seen what I saw on the south end for a couple of years, there is NO WAY I would not be armed there. THere are good people there, but the pukes are everywhere! Then again, being a paranoid cop, I go armed EVERYWHERE.
On the north end, there are some good shopping centers way up Veterans Parkway (4th avenue). pick up the significant other some stuff, and relax a while.
IF you have time, you may want to drive up to Callaway Gardens http://www.callawaygardens.com But if you're on a business trip I doubt you'd get that far up or have enough time to do anything there, you could at least drive up to Pine Mountain and see the overlook on HWY 27. Prettiest part of this country, IMO.
You ARE NOT PERMITTED to come to Columbus unless you eat at Country's BarBQue. Nearly everyone there can tell you where it is, but the one up veterans parkway across from LOWE's is where I go.
If you want to eat some REAL HONEST TO YOUR MAMA southern food, go to the Bulloch House in Warm Springs. http://www.thebullochhouse.com/ I have to pace myself when I go there. The fried green tomatoes are just like old times!! It is REAL southern cooking.
Don't know about the bar scene, not into it.
If you are into rivers, the riverwalk downtown is pretty cool, but if you go fishing buy a license, or one of my buddies may lock you up!! It costs a few dollars for a one day license, not worth the hassle for getting caught.
If you have any more ??'s, ask here or IM me.
What hotel are you staying at and where??
