The Four Seasons Restaurant came about when Bronfman hired Joseph Baum Restaurant Associates to make a restaurant to add value to the building. He decided to highlight American cuisine. Mimi Sheraton was on the research and testing team for the menu. The restaurant cost $4.5 million to open. It should be compared to the Guggenheim Museum which cost $3 million and was built at roughly the same time. It was the first restaurant to offer meals that changed with the seasons and was famous for its power lunches – JFK`s 45th Birthday dinner was held there. More recently there was a new renovation by Annabelle Seldorf in 2018.
