You know what I think would be best?
If we could somehow get the asian food places that have booths at Saturday Market to set up chop in the park across the street from the convention.
They're mobile, the park is set up for such things already, they wouldn't make more work for the hotel, we don't have to worry about getting clearance from the hotel or papers for food handling, they'd be easy to find for the attendees, and for the small ammount of trouble it'd be for the vendors to get there they'd make a LOT of money.
All we need is one food wagon with spicy noodles.
