Today in Japan, McDonald's is rolling out a Wi-Fi service today in its restaurants across the country. Here's the television commercial. Fascinating.

Customers who bring their DS units to McDonalds can download items and original content as well as play others via WiFi. Besides Pokémon mini-games and character downloads (Jirachi, anyone?), there are also McDonalds quizzes and even a McDonalds manga service.
