Those Rorscach-like QR codes seem set to join the fax machine as a technology embraced in Japan but left behind by the rest of the world. Even with the mass migration to smart phones, the checkered squares are everywhere, as evidenced by the QR code menu at Glass Dance (6-1-23 Roppongi, Minato-ku. 03-3475-6078). Never again will you feel pressured to make up your mind quickly as the waiter hovers over you. Download a free app, Znap, to your device, scan the code off your order and the waiter will have it to your table in a flash. They claim it’s the first of its kind in Japan.
