Welcome to the basement. The theme down here is now "recycle, reuse, reduce." We enter into the smaller half of the cafeteria. Do you want to get something to eat or do you want to see the Coal Mine? You can sit in this area or get some Captain Crunch ice cream. The back wall against one side of the cafeteria is filled with posters of the food groups.
