Digital menus can work when they are made for the digital format. Most Qr codes are just the menus that were made to look beautiful on paper and suck to look at on your phone, I don't want to have to open up my phone and jump between pages on two separate documents on my phone. It's also terrible that I have to waste my battery life to order food every time.
The ideal situation is isn't the China situation people are describing of scanning with their phone and opening an app or custom made site, it's the situation in Japan with a small tablet on the table everyone just puts their orders into and food is delivered as the orders are received when combined with a call bell for refills or asking questions. I don't have to install anything or worry about tracking.
