The Robot Restaurant in China has replaced human servers with robot servers. This particular restaurant in China employs these machines as its staff. The Robot Restaurant is located in China's Heilongjiang Province and it employs about 20 mechanical staff members. The robots prepare the food, serve the food and pretty much run the restaurant.
There is even a robot that will sing to you while you are eating if you would like. This restaurant does need some humans working there after all. The ingredients are placed in cabinets and are pre-loaded, so that the robot is able to make the meals. A human pushes a button that signals to the robots exactly what meal should be cooked. The Robot Restaurant is definitely a sight to see.
