I like the idea. I think some do a terrible job with it, doing little more than digitizing the print menu, with all of the tiny print. An easily scrolled list, with a fast loading modal with more details when tapped, would be far better. Take it one step further, let me create my order, and then show the server a QR code. As they go to each person on the table, they can still answer questions and take the order on the fly if they need to. tldr; It's a UI/UX problem that can be fixed. The idea itself is sound.
