Oh, that's a total gamechanger. If looking at the QR code menu allowed me to also order from it, it would have made it much superior to physical menus, no argument. Sadly, I've never encounteted it across many restaurants with QR code menus in a major city (Seattle). Every single time it was either a link to the pdf version of the printed menu or their website with the menu.
Order and pay is the standard these days in Australia. It's pretty rare to find somewhere that has the menu but nothing else as a qr code (why not just look up the restaurant's website in that case?).
