In a few small cafes I’ve noticed the same issue with paper menus - every small change means reprinting the whole thing again, which adds up over time.
QR menus have basically solved that problem in a lot of places.
I came across
https://www.splento.com/splentify, and the idea is clearly built around making menus easier to update digitally instead of constantly printing new versions.
For restaurants that change prices or dishes often, it feels like a much more practical setup overall.
