If you are looking for a place where you can hang out and use free WiFi, the Pioneer ChaTime - is a good place to go. They give you a password for their WiFi network and they even have extension cords provided for each table. If you like white, pink and purple - which I think a lot of young people like - you will dig their decor.
While you're there - try all of their tea varieties. Did I mention they also serve food?
