I have an old WDW book that was published in the early 1990's, which mentions a restaurant called Top of the World, located on the top floor of the Contemporary Resort. So far, I have found no mention of this in more recent books or online, and it appears that this is now the current location of California Grill. Was the name of the restaurant changed from Top of the World to California Grill, or did California Grill simply replace Top of the World if/when it closed?
