I'm not really convinced by the "intentionally inaccurate" arguments (if they want to deceive, then surely they could also just serve a fake PDF to Googlebot).

I'm not really convinced by the "intentionally inaccurate" arguments (if they want to deceive, then surely they could also just serve a fake PDF to Googlebot). But I suppose it's reasonable to assume that restaurants would be less likely to keep their metadata up-to-date than they would their PDF menu. Unintentional inaccuracy, in other words.
