Is a digital photo menu worth it compared with print?

Yes, when the new dish's photo has to be on the table this week and the printer cannot make it. No, if the printed menu with a few photos reads better and barely changes. See whether the last new photo waited on a reprint. In Madrid the new dish is served for days before the printed menu shows it. The QR publishes that photo the day the dish comes in, and paper is updated only if it is still on the table.
