I think the customization aspect is overrated. In a blind taste test I bet prepackaged salads and hand made ones would fare about as well. Just like how cheap and expensive wine are indistinguishable under a blindfold. And that's what's so funny about this story. Two hundred years ago all salads were hand made. Then we invented machines to automate it. But then automated food got a somewhat arbitrary and unjustified stigma about it, which allowed for hand made salads to become a thing again. Similar to how an artificial social stigma was constructed against "fake" furr, in preference to animal furr. There is virtually no visual difference, but rich people wanted to maintain the signaling-value of the more expensive "real" furr and did so by sneering at the cheap-to-manufacture fake stuff, which propagated out in the rest of society in the form of adverts and the like.

And of course the same thing will happen here too. Now robots can make "hand made" caesar salads. But eventually the same social constructions will be created against that and in preference to man-made "hand crafted" caesar salads. Under a blind taste test man-made and robot-made foods will be indistinguishable but without the blindfold there will be enough culture and clever rethoric created to trick the senses, and we'll be back to where we were a few years ago.
