With no instructions, I order the two items through the Presto. Beautifully lit photos let me see what I'm going to get. The UI is intuitive. Within 20 seconds, I've sent my order to the kitchen. Before we'd even finished eating, I swiped my card slightly awkwardly into the built-in payment slot, added a tip, and settled up. I would not say that this machine will blow your mind with its technical capabilities, but that's exactly the point: It just works.
