In Great Falls, Montana, inside a local motel, there’s a tiki bar that was built in 1962, when Polynesian themes were popular, The Sip 'n Dip Lounge features 80-year-old living legend and great-grandmother "Piano Pat," who has played piano there since 1963.

In 1995, as a "fun factor," they added women dressed as mermaids swimming underwater in an indoor swimming pool visible through a window in the bar. Together, they draw people from all over the world. In April 2003, GQ Magazine named the Sip-N-Dip Lounge the #1 bar on earth!.

CBS Sunday Morning ran a good piece on the bar.
