I think a lot of them go simpler than you seem to be thinking. Even when I went to those in SF or Philly, for a couple days there wasn't a sit down nice thing, just a coupon to a few local restaurants, or some sandwiches or something.

And while one you went to may have had sushi rolls, well, don't eat it if you don't know what it is. The majority of the local WordCamps I've been to have been pretty freeform on lunch.
