I have always believed that the Mystery Drink was created at the Mai Kai and copied by the Kahiki. I had wondered why my early Mai Kai drink menu copyrighted 1957 did not have it in the list. I knew it came later. In fact, I was told this last weekend at Hukilau that it was first served in 1962.
The Kahiki opened in 1961. The oldest menu I have from there has the Mystery Drink on it. The bowl it shows on that menu is exceedingly rare. That bowl shows up in a few pictures of celebrities at the Kahiki from those early days. But for the Kahiki to copy the Mystery Drink, it would have to come at the very earliest, in 1962. More likely even later.
If there are images from their opening showing the Mystery Drink, dated 1961, then the invention of this classic height of Poly Pop is now in doubt. I will search out my own archives later for the photographic evidence. Post your pics if you have it already before you.
UPDATE: The Kahiki ran an insert in the newspaper on September 24th, 1961, with an image of the Msytery Bowl, and mentions the Mystery drink and where the Mystery Bowl was made. That stamps a clear date on the Kahiki Mystery Drink as 1961. If the Mai Kai served the first Msytery Drink in 1962, they were copying the Kahiki.
Does anyone have more proof on the Mai Kai doing a Msytery Drink before 1961?
UPDATE 7-23-07: Kern Mattei, GM of the Mai Kai says the Mystery Drink was announced in their “Happy Talk” newsletter. If you are in possession of a pre 1961 “Happy Talk,” please check it for mention of the drink and report the facts!
UPDATE 7-30-07: I asked Mimi Payne, who runs Arkiva Tropika to look through her collection for a Happy Talk to try to prove this mystery. No luck on the Happy Talk, but, she did find in her collection that the Okole Maluna Club menu had the Mystery Drink on it, and was dated 1958. Sure, that’s not 100% factual, but, nobody is going to make up a date on something like that. I consider this proven. The Mai Kai invented the Mystery Drink. Proof.Â And far earlier than was thought.
