This is my favorite location and bubble tea place. For something heavy/dessert-y I recommend: brown sugar roasted milk tea with half sugar and less ice. For something light: mango qq without the tapioca or honey lemon green tea with aloe vera. Always reduce sugar to 30% if possible (for honey and brown sugar, can only reduce by half).
The lines are long during weekends but they move fast. It's very happy location with tons of people that just hang out after dinner. Though during weekends and evenings do not expect to get a seat, this place is packed. I've always taken mine to go so did not have these issues.
