I agree, I don't like having to scan a QR code to read a restaurant menu on my phone:
A couple things. First, I don't think too many restaurants do this so they can change the pricing quickly and often. Why do I think that? Because most of the menus I see on my phone are just pdf's of the old school menu--although sometimes you're taken to a web site, but I have a hard time believing someone is constantly adjusting prices on a web site.
And second, while I understand the possibility that someone could put a fake QR code on your table and thereby install malicious software on your phone, my visit to a restaurant in Coyoacán this past week showed what I thought was a reasonably unhackable way to display the QR code:

No one's going to laser-cut blocks of wood and swap them out with the restaurant's just to install malicious software!
I still want a handheld menu, for a variety of reasons, but I thought this block was cool.
