The theme was "pirate" with a good dose of Polynesian Pop, especially with the drinks.
This was one of the eight (at least) restaurants operated by the Specialty Restaurant company in the LA area that had various degrees of Poly Pop and Nautical themes.

Most people associate Pieces of Eight with the cocktail of the same name which originated here and was later re-printed in Beachbum Berry's Re-Mixed.
Pieces of Eight: ½ oz Lime juice, 1 ½ oz Lemon juice, 1½ oz Passion Fruit syrup, and 1½ Aged Rum.
Shake or flash-blend with crushed or pebble ice. Pour unstrained into a tall glass, goblet, or tiki mug. Top with more crushed ice if needed and garnish with a lemon slice, a pineapple wedge, an edible flower – or all of the above!
