Not everyone can cook, but many people might find it informational and/or useful eventually to know how their meal was prepared.

In some restaurants, you can't see how your food is prepared at all, and you judge based on your knowledge and experience of prior meals.

Some restaurants will openly show you the preparation of the food (to display that it's freshly made, reassure that there's no microwaving going on, etc).

And in most cases you can look up recipes online to try your own hand at recreating a similar meal - although often without the same tools, experience, ingredients and precise recipe, it might be tricky.

Ultimately I think it'd be wonderful for all recipes and instructional information to be available for anyone to view and try themselves if they so desired - it'd also help people understand what goes into the food that they eat (and pay for).
