Mall Scavanger Hunt !!!

I am having a birthday party next month but i want to plan now it will be coed and a mall scavenger hunt! i need a list of items in pictures and actaull items. Also i think it would be fun to have clues! theres going to be alot of kids like 25 and i called the mall to make sure it was okay so thats not an issue. I also need ideas for what to do for food because i dont want it to cost to much! thanks!!!!
