The fear with QR menus is that they turn a warm room into a self checkout. It is a fair fear, and plenty of them do. But that is a design choice, not a rule.
The menu is décor
Your printed menu was never just information, it set a mood. A digital menu should do the same. Whitewashed calm for a seaside place, warm wood for a mountain grill, crisp and quiet for fine dining. When the screen matches the room, the customer never feels handed off to a machine.
Keep the human on the floor
A QR menu frees your staff from reciting the same specials forty times a night, so they can do the part a screen cannot: read the table, recommend, pour, welcome. Technology at the table works best when it makes the people at the table more present, not less.
Choose a theme that looks like your room, keep prices honest and current, and let the QR do the boring part so your team can do the hospitable part.
