This has all been done in Japan for 5 or 6 years now. There are plenty of Izakaya in Japan that you order from wireless color tablets. They have the entire menu in color with pictures of every item. They've been around since at least 2005. (Izakaya = the type of place Japanese people drink which is most easily described as booze and tapas)
