Behind the children's refreshment bar is a small sink tucked away in the corner of the bump out of the foundation, another good use of otherwise wasted space. It's not easily visible because it is short, so it may be easily reached by small children to get a quick drink of water, to wash their hands before eating, and to rinse the dirty dishes after lunch or snacks. Underneath the bar is a mini-fridge stocked with bottled water, fruit juices, yogurt cups, cheese bites, and other healthy snacks.
