Robotic, unmanned services on rise in restaurants
A 34-year-old owner of a French restaurant surnamed Lee recently purchased and installed tablets on all the restaurant's tables, enabling customers to browse the menu and place orders without a waiter. “It cost only between 200,000 won ($152.10) and 300,000 won to purchase one low-budget tablet, which I think well covers the work of one human server all day long,” Lee said.
