From Tiki's Grill & Bar:

"20oz Ceramic Mug, Haka. The haka is a ceremonial dance in Polynesian cultures. It’s a customary way of welcoming visitors, and also a show of physical prowess. The haka is still an embodiment of cultural pride, strength, and unity throughout Polynesia.

This mug is very similar to the previously issued Tropical Itch tiki mugs, but with a rectangular decoration on forehead and different glaze.

Advertised in their menu as an add-in for any cocktail served.
