The Sip 'n Dip Lounge in Great Falls, Montana has a most unusual attraction: an indoor aquarium stocked with girls dressed as mermaids. The Sip 'n Dip has been around for a long time; and is the premier attraction in Great Falls. It's an appealing tiki bar. The mermaids, added in 1995, were six local girls who swim while wearing fishy costumes. Because the tails preclude much movement, they must have strong arms.
It's a nice place to visit and have a drink!
