I tried the uji crystal matcha drink which comes with mango tapioca. Matcha taste was good and quite strong (kind of reminds me of Starbucks since it's kind of thicker and latte like). I liked the texture of the tapioca it doesn't get hard and stays chewy throughout, but the mango taste was not really there.
Overall enjoyed it but is a bit on the pricier side for a drink ~ 6 bucks for a medium (smallest size). Service was nice here though!
