Not wings suggestions because the best places in Athens are wings delivery.
But my favorite pre-drinking place is Taco Stand if I have to go to a bar. You will be better staying on the lawn where the arches are. It should be a great atmosphere, and you won't have any trouble from anyone being from the opposition as long as your not a cocky punk (I will assume this is not the case).
After the game, I suggest going to Boar's Head. The Mellow Mushroom there used to be great, but they have moved locations and the new one is not as good.
When I was there, I think there were 62 bars downtown in a 4 x 4 block area, so you won't have any troubles finding a place to drink.
If you are a strip club fan, you are out of luck. Not a problem for me because I don't really care for them but Toppers downtown is the only choice and I hear that it is awful from my friends that like going.
