Very cool to see. It’s a chocolate fountain, or more of a chocolate flow from the ceiling down to the floor through various funnels. BUT, be on the lookout for it or you will walk right by without noticing. After your exit the Conservatory, walk to the left, back toward the restrooms and shops down that corridor. The fountain is on the front right corner of the chocolate candy store, on the right. It’s name is Pet… some French sounding name that I’m sorry I cannot spell.
