A friend mentioned this to me when I was back in Hong Kong: Young professionals, after overworking themselves far past midnight, gather in McDonalds armed with… PSPs and Nintendo DSs.
Even though they are strangers to one another, they will get together for a good multiplayer game of, say, Monster Hunter. It’s popular enough that one local gaming magazine published a list of McDonalds to play.
They even offer 20 whole minutes of free Wifi! (Free Wifi is not easy to find in Hong Kong.)
