When they became widespread during the covid lockdowns they were a good solution when we wanted to avoid spreading things by touch. Even how, as long as you can still ask for a printed menu, I think the QR code menu is a reasonable default as long as the menu is relatively simple. If there are a lot of options it becomes cumbersome. Now, I f you have to order through their menu site, that almost never works well. Those sites are just not well run enough to pull off ordering well.
