To start the plan rolling....
I like Mantus' suggestion of Gabby's. It's your basic pub with a patio and it's right downtown, a few blocks from the CON.

According to the CON website, it closes at 6pm on Sunday. So why don't we plan to meet at Gabby's around 6pm.
As for the CON itself, I'm just going to check out the Vendors' area in the afternoon. I don't want to pull any of you away from the specific events, so if I see you there, great. Otherwise, I think I can hold on until the evening.
