The Mickey Mouse Theater stood on the exact spot where Pinocchio's Daring Journey and the Village Haus Restaurant sit today. The entrance to the Welch's Grape Juice Bar can be seen at the very far left.
In 1965 the theater was renamed the Fantasyland Theater (and you could catch a humdinger of a show there that summer called "Humdinger!"). The Theater and the Juice Bar were torn down in 1982. Nevertheless, this particular area of Fantasyland has left a purple stain on my heart that nobody's ever been able to wash off. .
