King Harvest makes hummus, has for years.  So they wanted a factory feel to their coffee shop, and a window onto the factory floor.  Due to safety concerns, we had to keep the window too high for the kids.  So in an old pile of junk out back I harvested an old door and made a peek-a-boo for the little ones.  the King himself places comics and pictures behind the safety glass inside the door, providing a fun little treat for any curious kid (and the glass keeps their fingers away from the factory)
