I'm not sure why but I tried to connect to Nintendo Zone at McDonalds today and it said this service has been discontinued. Anyone else have that problem? Could it be just that McDonald's? Or that I moved to a new state?
Based on this link from Nintendo Support, it sounds like Nintendo Zones in McDonalds are closed. BestBuy and AT&T still work, and it sounds like you just have to connect to the wifi & then go up to the 3ds on the second floor.
