I like that you can customize things like your sugar and ice levels in your drinks. Their drinks are also consistently good, but my favourite has to be their most popular, the milk tea. I can't remember what it's actually called, as I just order a "number one". As for extras, I only order tapioca. Their bubble tea is honestly the best I've ever tried.
The decor is also modern, but the bathrooms are hard to find. And prices are moderate.
However, on weekends, particularly in the evening, there are literally lineups out the door. And it doesn't help that the staff don't make drinks quickly. However, in spite of the aforementioned, their bubble tea is still good enough to make me come back over and over again.
