This is a great idea for pranks! Although real people who go to restaurants and don't spend their time on Reddit may not know what a rickroll is.

It could be funnier to replace the menu with a slightly fake one and see what happens when people try to order things that don't exist (but could reasonably be thought to exist).

Or outrageous items. Let's experiment.

I love that -- thanks! I have a lot of sympathy for what motivated restaurants to adopt QR code menus, but as a patron I hate 'em. If this prank is done at scale it can help drive the restaurants back to real menus.
