Any recollection of what it contained? Though I'm guessing at that age, you didn't have the "taste catalog." (Perhaps you could compare it to a Sydney Apple, which I'm told you are fond if.

)
Looking at the bar list, it seems like it's more in the cocktail realm than the super-strong multi-liquor mixed drinks category. So I'm guessing it was something somewhat simple to make?
There's also an item on the list, in the non-alcoholic list, called a "QE2 Fruit Punch." What makes it "QE2," I don't know. And of course, the QE2 Single Malt, for $27.50 in collectable bottle, and $5 QE2 Miniatures.
