This is a blue bucket shaped mug marked "The Original Chuck's Steakhouse Waikiki." It has a repeating Greek Key design around the top and bottom edge and is glazed in a dark cobalt blue with white lettering.

It was most likely issued by the Chuck's at the Outrigger Waikiki Beach Resort, which closed its doors at the end of March 2018.

The Outrigger location is "original" as it appears to have been where the original restaurant moved to after the closing at the original Edgewater Hotel location.
