 When built in the 1960s, the O'Haire Motor Inn was considered "swank" and modern, and the tiki concept was popular, in part due to the then-recent admission of Hawaii to the United States as a state.The concept of a tropical theme was also viewed as a fun concept for Montana, a landlocked state with long, cold winters.Though tiki bars in general declined in popularity in the late 1970s and 1980s until the revival of the style in the 1990s, the Sip 'n Dip survived with few changes.
