I've never seen a Tahitian Sunrise but I have drunk a few. Here's the recipe if you are interested.
1oz Mango Rum
1oz Banana Liqueur
4oz Orange or Tangerine juice
Pour all ingredients into a shaker full of ice, shake to blend. Fill a glass with ice and strain the mixture into it. Top with a splash of Raspberry or Grenadine syrup
