A restaurant menu customers open on their own phones by scanning a QR code at the table, instead of using a printed menu.
QR code menus became widespread during the COVID-19 pandemic, when restaurants wanted to reduce shared surfaces, and many kept them afterwards. Scanning the code opens a web page or PDF showing the menu. More advanced versions let guests order and pay from their phones, sending orders straight to the kitchen and reducing waiting time.
For example, a busy rooftop cafe might place a QR code on each table so guests can browse dishes with photos, see allergen information, and order another round without waving down staff. Menus are easy to update when prices or specials change, with no reprinting. Downsides include frustration for guests without smartphones or reliable data, and some diners prefer a printed menu, so many restaurants keep paper copies available. Codes should link only to the restaurant's genuine domain.
