A QR code is useful when it points to a stable, readable menu.
Start with the right information
Group dishes clearly and supply current prices, descriptions and availability. Include a plain contact option for guests who need help.
Put it into practice
Publish the menu and create a QR code for its public address. Scan it on more than one phone, with the camera at the size you intend to print.
Check before you share
Update the existing page when prices change, then publish again. Keep the address stable so printed codes continue to reach the menu.
Original guidance for this installation. Connected services, available formats and prices are shown in the workspace before you use them.
