Stateside DS gamers can already get online using free WiFi at McDonald's, but now Nintendo's bringing a slightly different version of the service to Japanese McD's: customers can log in to get menu information and download free game demos. The service is being rolled out at 21 Tokyo-area restaurants with an assist from NTT, which also provides DS wireless service at Japanese train stations, so things should get lit up fairly smoothly. You'd better hurry if you want to join in on the fun, though: the test program ends on December 28th.
