At the time of a circa-1966 layout, the Diamond Head Wing has just been completed. It consists of 3 floors; the Street, Mall and Third Levels. The complex now encompasses 1.3 million square feet, making it one of the largest retail centers in the fifty states.

A revolving restaurant was on the 23rd floor of the Ala Moana Building. La Ronde opened for business in November 1961 and was one of three food service facilities in the office tower. The L'Omelette Coffee Shop was on the 3rd floor. The Belfry was on the 20th.
