Many Sci-Fi movies have long shown autonomous flying robots taking care of menial tasks like delivering lunch, doing repairs etc. The future is here and it's taking on the food-service  industry first.

A British sushi chain called 'YO! Sushi' has unveiled a flying food tray at one of its restaurants in London. It brings orders to customers and prevents staff from having to do anything more than simply watch the drone's progress.

The iTray, which is controlled by an iPad, is the 21st century novelty version of the waitress on roller skates and comes equipped with a camera so employees in the kitchen can make sure the food has been brought out and the customer has not been wounded by one of the four rapidly spinning blades.
