Had Walt Disney's original plans come to pass for his park, the very lovely Enchanted Tiki Room would have come to life as a sit down restaurant in Adventureland. For the day, this would have been quite the unique experience. Imagine sitting under in the beautiful Hawaiian inspired room enjoying a meal while the Tiki Birds serenade. The concept art shown is a fairly rare piece as it portrays tables placed inside the room and guests walking around in it.
Personally, I'm quite pleased the Disneyland Imagineers went an entirely different direction. Had they made this a high end restaurant, only select number of paying guests would have been able to experience the earliest incarnation of Audio-Animatronics. As a continual show, Disneyland guests had a chance to see the latest and greatest Imagineering technology without having to pay more.
A more thrilling show could be found in Adventureland anyway. A full on South Seas revue at the famous Tahitian Terrace- complete with hula girls and fire dancers providing more excitement than a group of machine birds could ever compete with!
