The government that governs least, governs best. It is not the role of the government to impose the additional burden and expense on businesses, that will ultimately be borne by consumers, to comply with some politician’s whim about what people need to know.
The free market will deal with the situation very nicely without need for government interference. If there’s demand for this kind of information then restaurants, pursuing their enlightened self-interest, will provide it.
You said it better than I did. Thank you.
