Located inside the premises occupied for 20 years by a fish and chip shop, first known as Mr Chippy and later rebranded as Hook & Line.
Owned by Maria Pavlou and her partners who also own Vudu Lounge and have run it since 2004 in the same building.
The name "Dum Dum" comes from the Moai character in the Night at the Museum movies.
The interior is what they describe as "Tiki Modern" by which they mean sparse and uncluttered without doing the immersive decor that is familiar to those tikiphiles who are used to the old school standards set by Don the Beachcomber and Trader Vic's. Dum Dum's booths and stools incorporate rattan and earth toned vinyl padded seating. Walls are covered with tropical leaf prints. A couple of walls feature fake foliage and neon lighting with messages like "Welcome to the Jungle" and "Rum, Forest, Rum". Ceilings are lit with swag lamps and the space over the bar is draped with several dozen fake flower leis. There are a few small foot-tall Moai statues on one wall, but no large carvings...and especially with the bar's name, it seems like there should be at least one massive Moai on premises, even if carved of foam or fiberglass. Artwork and decor is lacking, but this stripped-down space is more focused on the club crowd who are there to dance.
That said, they appear to have a thriving cocktail menu with a variety of their own concoctions as well as old standards to choose from... and they do serve drinks in tiki mugs.
