Please review the information about food, here: http://allunschoolingminnesota2013.blogspot.com/p/food.html (If you're reading on the blog, it's one of the tabs above).
The lunch break will be nearly two hours long, so people will have time to go to a grocery store or restaurant. We can't have food in the conference center.
Please read again about the restaurant, and where the nearest stores are. I don't want anyone hungry, especially kids. I wish they would just have let us "monkey platter" it. And their conference catering is way too expensive. :-)
Be prepared, and bring some groceries for the room.
