That is my favorite Couples drink. For me, the mix depends on the size of the drink! My best guess would be for say 8 oz of orange juice try one shot of coconut rum, 1/2 shot of Amaretto and a squirt of lime juice. Shake up with a lot of ice and see what you think. You may want to modify the amount of rum and Amaretto to suit your taste. I found it to be a standard offering at CN but I had to teach the bartenders at the other Couples to make it. I think some may call it somethig else. Good luck!
