Boba tea... a.k.a. Bubble tea, Tapioca tea, Pearl tea
Thanks! I'll try Coco's. The Tea Lounge selection/menu is amazing (160 items)--download it from their website or pick up a to-go menu. I loved the iced "mocha coffee with tapioca." Many of their teas/drinks are available hot or cold. They have specials on FourSquare so be sure to 'check in,' and there's an ongoing special of "buy 5, get 1 free." Their Happy Hour is Mon-Thurs 10am -2pm: BUY 2, GET 1 FREE. Oh, and you can bring a used board game and donate it for a free tea!
They have free wi-fi, but there's not a lot of seating. Check out their website: http://www.tealoungetx.com
