Yes, The Domino Pizza is on your iPhone now. ^^
According to the website from the Domino.jp, you can now download application for your iPhone through App Store now. Then you can order your Domino pizza even at the street. With iPhone’s GPS support, they can send it to your current location.
Nothing much to say, just watch the instruction Video ^^ :
Not really going to try it since Pizza is expensive in Japan. Might consider ordering it if getting too hungry and almost faint on the street… ^^”
