The bubble tea is tasty, the matcha cakes are nice (albeit a tad small), and the service is great. I like being able to modify how sweet the drink will be and how much ice is included (I recommend slightly or half sweet and the least amount of ice). There's also a wide variety of extra ingredients (toppings?) that can be included to customise your drink - but I haven't strayed from the usual tapioca balls.
I've had a few of their milk teas which have all been great. My favourite so far is the classic taro milk tea.
I'm not so sure if the price is comparable to other bubble tea places but it seems a bit expensive to me. That's the only downside I can think of!
