The Royal Tahitian, built in 1960, and opened June 24th, 1961, claimed to be the world's largest Polynesian restaurant, with 250 acres of tropical landscaping and "lagoons" -- however, this was simply a reference to the Ontario National Golf Course next door. The main floor was the restaurant, with a bar downstairs, and a show area outside. It featured a dramatic asymmetrical swooping A-frame entrance.
In later years, after the Royal Tahitian closed in 1967, its building became the club house for the golf course. In 2003, the building was set to be demolished, but it lingered for several more years and was torn down some time after 2010.
Just down the street there is an apartment building built in 1962 (now the Whispering Lakes Apartments) that once featured some large Milan Guanko tikis, and still retains some Polynesian influence.
