The Tiki vibe here suggests that the name of the cocktail is a reference to the world famous Hawaiian surf break the "Banzai Pipeline", usually shortened by those in the know to the "Pipeline".
Unusual, but rather moreish… I may up the sweetness next time (personal preference). There will be a next time. Curious as to its origin and popularity. I get snow-topped peak vibes from this… Nice addition to the site.
