QR code menus spread quickly across European restaurants and cafes and became a permanent fixture for good reason: no reprinting for every price change or seasonal item, and a menu that's always current.
What a good QR menu page needs
More than a static PDF, a real digital menu page should show clear pricing, dietary and allergen information (genuinely important across the EU given labeling expectations), and ideally a direct way to order for takeaway or a booking block for reservations.
Static vs. dynamic, again
A dynamic QR code on the table means the same printed tent card keeps working even after a full menu redesign or a location move, a static code baked with today's address doesn't survive either change.
Print the code once, keep updating the actual menu behind it as often as you need, that's the entire advantage over a printed menu.
