Why QR only menus exclude customers
A QR code is not an accessible menu
A QR-only menu assumes a customer has a charged smartphone, mobile data, a compatible device, enough vision to scan the code, and confidence navigating an unfamiliar website. That is a lot of assumptions for a bowl of soup.
A genuinely inclusive setup is simple: keep a printed menu available, use readable type and strong contrast, make the QR page keyboard-friendly, and let staff take an order without treating the request as an inconvenience. The printed version should not be hidden behind a performance of asking nicely.
Digital options can be useful. They are not a substitute for offering a usable alternative.
