This is the "The Tiki Bar Moai Sharing Bowl" made by Garnet McCulloch at FireWorks Studio in Glasgow, UK. Not sure if it's actually in use at 'The Tiki Bar and Kitsch Inn' in Glasgow yet as this is one of the early prototypes. A rough black exterior glaze with a smooth swimming pool blue glaze in the interior of the bowl part. The whole item measures 8" wide and 6.5" tall with the bowl itself having a diameter of 5" and a depth of 4".
