the qr code menu is a popular thing these days but every time I have used it, it takes you to the buisnesses web page where they either have the info instantly available or its a PDF. Typically they have a paper copy in cases where someone wants one. Its a popular trend since covid.
Embrace it people, its not the end of anything.
The lack of a real menu and handing you a piece of paper with a QR and a bunch of AI shit, is ugly and I would honestly think twice about what the food quality is like there
