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.

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.

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.

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

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.
