I have tasted unusual varietals of banana, mostly from SE Asian supermarkets, that taste very close to artificial banana when they are super-ripe. I have a sense for it too, because artificial banana used to be my favorite candy/popsicle flavor as a child. Full disclosure though, I probably haven't tasted artificial banana in at least a decade.
