So I figure we should do this as the year is winding down. Unfortunately, the last weekend in September is during CARMEGGEDAN TWO: THE WRECKONING. It seems like the GroupThink (sorry, Phil) has spoken in favor of karaoke, perhaps in Koreatown.
So: any dates jump out to people? Weekends are usually quite busy, so a private room in Koreatown would be ideal in that situation. Otherwise, there is always Gabe's.
Since the date is no longer tied to a game, it could be any weekend (except for the WRECKONING, as already mentioned).
