They've been rated among the ten best restrooms in America. The spacious facilities have clouds painted on the ceilings, with some sinks lighting up the water streams -- red for hot, and blue for cold.
Field Museum bathrooms are family friendly, with a private nursing room for moms and child-sized accommodations.
The restrooms are cleaned once an hour due to high traffic.
