Well ... yes, in the sense that it was very good and prices were very reasonable (at least, comparable to what you'd pay at someplace like Starbucks or Coffee Bean). I had the iced raspberry black tea and it was just perfect for a hot day. But it's just an outdoor kiosk selling a dozen or so types of beverage, it's not a whole shop. It's hardly more than a snack cart. So I mean, it's definitely worth doing if you want tea, but I wouldn't necessarily make the trek from Camp Mickey Minnie just to get some.
They don't take dining plan, btw.
