 Decorated with a bamboo ceiling and a South Seas theme, the bar also features "Piano Pat" Spoonheim, who has played piano there since 1963 and is noted for her unique "jazzy" style.The mermaid concept was introduced in 1995, when there was a revival of the tiki fad, and it was the brainchild of the bar's current owner, who wanted to add a "fun factor".It became popular, particularly for Montana, a landlocked northern state where a tropical tiki theme is unexpected.
