When people talk about hidden variable theories they still assume a definite answer exists.

I'm saying the answer doesn't exist because the question is not really valid in some sense.

Which kind of coincides with the idea that "the observable doesn't exist until measured", but I'm taking a little further and saying, it doesn't exist even when "measured" because you're not really measuring the thing you think you're measuring.

It seems to me there would still be a fact of the matter as to whether the person would enjoy a particular type of food prepared in a certain way, in a certain context, even if that situation never occurs or is considered?

That's the point. Something is the matter of fact, but it's not what the original question was. The original question is bogus. The way you perform the "measurement" influences the answer you get.

Also if you repeat the measurement multiple times, results will change.

From my personal experience, I didn't like soy sauce at first, but then I got used to it and started to really like it.
