I love Nachos, too; but this story sounds a lot like the story of the creation of the Caesar Salad:

Reminds me of the 'Buena Vista' in SF, they claim they invented the "Irish coffee drink" I mentioned that to a bartender at ;Fidler's green, on Columbus a few blocks away, He laughed and said: "I'm pretty sure Irish men have been putting whiskey in their coffee long before the BV came around.
Similar could be said about putting cheese on chips.
It’s sad that people are told bad things about anchovies. I never had anchovies for years. But one side tasted them They are great. And healthy too.
