I know it is early to be thinking about this . . . but:
I'll be making my way to Austin in the fall for a conference and am charged with organizing a dinner get-together for a group of 20 friends. Almost everyone in the group is in their 20s and 30s. Something Austin specific, good food/liquor, and walkable from the convention center area would be particularly helpful. The last time I was in Austin I was taken to Moonshine and found myself reasonably pleased (although the entrees were a little less impressive than the rest) and will hold it in my back pocket if I don't hear a strong suggestion for another place.
