I am not sure if Taro milk tea is usually supposed to be chunky...I have had many but never one with a more chunky texture to it. Instead of being turned off, I actually didn't mind it at all. It gave me the feeling that purple yam was actually a main ingredient in the product.
Usually, bubble teas leave me with a grainy feeling. This is most definitely the flavouring powder and sugar. I was happy when my bubble tea here did not taste like that. Additionally, the tapioca had the perfect bite, A+
From my impression, Chatime has friendly service and quality products.
