Opinions of Montana’s notorious mermaid lounge vary greatly. Bring up the Sip ‘n Dip Lounge in Great Falls and you’re likely to be met with comments like “The food isn’t that great” and “I don’t get it. Why mermaids?” But even skeptics must admit that the Treasure State wouldn’t be the same without the Sip ‘n Dip, which is part of the O’Haire Motor Inn and the quirkiest restaurant in Montana.

The very concept of a tiki bar in the middle of Montana is totally unique.

Twyla A / Yelp The unexpected tropical drinks and seaside vibes just add to its appeal.

The Sip ‘n Dip Lounge opened in 1962, a time when Polynesian themes were popular.

Allison J / Yelp The O’Haire Motor Inn was considered modern and trendy at the time it was built. The idea of having a glass wall behind the bar that looked into the indoor swimming pool was inspired by a similar design the builder noticed when he visited the Playboy Club in Chicago.

The food served here is good, but it’s the tropical drinks that draw people in.

Twyla Y / Yelp They come heavily garnished and beautifully presented. It’s easy to have quite a few.

You can catch the mermaids nightly at 6 PM (except for every other Sunday, which is Mermaid Brunch day).

Most patrons agree that the true draw of the Sip ‘n Dip is Piano Pat.

Montanabw / Wikipedia Pat is an octogenarian and a great-grandmother. She’s been at the piano since 1963 when she accepted the job as a single mother supporting her three children. Pat belts out covers of familiar songs, with “Sweet Caroline” being the most requested.

Needless to say, this place has received national attention and has even been visited by celebrities.

Jeremy D / Yelp GQ Magazine once listed the lounge as the “#1 bar worth flying for.” When Daryl Hannah stopped in with Nick Nolte in 2002, she ended up putting on a mermaid tail and swimming in the pool.

Whether you love it or hate it, you must admit that there’s no place in the world quite like the Sip ‘n Dip.

The Sip ‘n Dip may be our most unique restaurant, but it’s far from the only quirky place to have a meal. Here are some of Montana’s other one-of-a-kind dining establishments.
