"I think crypto will slowly percolate its way up and people will adopt it gradually as user friendly, cheap products, become available."
- Neal Stephenson

Electric Menu  
  Ordering of food is automated, without waiters.  

I paused as we passed an automatic dinner service. With a nod she assented to my enquiring look and we passed inside. A courteous robot ushered us to our tables and placed the electric menu before us. We surveyed it, chose our requirements, and then pressed the corresponding buttons arranged at the side of the menu. Instantly the table top turned over and there was our meal upon metal plates. This “turnover” was effected by tremendous centrifugal force which naturally prevented the viands from hurtling off. I would mention here that the idea of tabloid food had never really attracted anybody, and the food of 2,000 was about the same as it had always been, save for the fact that there were many cultured, delicious dishes from future ages.

I was going to do a Science Fiction in the News article on this Technovelgy item, but then I realized that it would be about ten years too late! I do know of one restaurant that still uses them, but they're just trying to get the last bit of value from the iPads they bought twelve years ago.

Anyway, here's how they work.

Today (2022), I think the latest incarnation of the "electric menu" is the digital menu, which you pull up on your phone using a QR code on the table.

Compare to the mirror menu from Caesar's Column: A Story of the Twentieth Century (1890) by Ignatius Donnelly.
