Restaurants in Europe, the United States and Japan are testing technology to let diners order their food direct from a screen at their table instead of depending on a fellow human being to note their choice.
Besides cutting costs, companies that sell the “e-menus” argue the bytes-for-bites way has a new value that can attract younger customers, and various photographs of steaks and gooey desserts attract diners to order more. It also could extend the TV dinner. How about a computer game dinner?
“It's about impulse-buying,” said Adi Chitayat, Conceptic’s CEO. “If a person starts looking at pictures of chocolate cake, the chances are he'll order it.” Frame, a restaurant in Tel Aviv with the system, is said to have its sales on tables with the e-menu increased by about 11% . Customers often call ahead to reserve （预定）spots equipped with screens, manager Natalie Edry told Reporters.
At one of the e-menu tables, IT worker Gil Uriel and his young family were enthusiastic as they checked out pictures of the dishes on offer and squabbled（争吵）overdesserts. “It’s more visual,” says Uriel, as his children clicked away furiously on a games function between courses. “We can still choose, we can still argue —but it’s much easier when we can all see it.”
