A tiny, darkened hallway tucked away at Kidcity children’s museum leads to a new and cozy, wondrous room that evokes a piazza in Melilli, Sicily, just before dusk. A faux marble fountain of dolphins leaping high into the air seem frozen in time as the smell of coffee wafts from a cafe in the corner, and royal green handkerchiefs, scattered on the stone-like floor, are pushed into tiny portals by little hands.
