Drinks
The drinks I've tasted from this Ten Ren's (that I can remember right now) are the Roasted Oolong Milk Tea, Sagittarius, Virgo, and Lychee Strawberry slush. All of them were pretty tasty, would definitely recommend the Oolong Milk Tea and Sagittarius drink.
Price
This is the reason I left out two stars. I've paid $15+ just for two bubble teas, and it's $7+ just for the Sagittarius drink alone (can't remember exact price, and this is even before tax).
Service
I'd say the service here is pretty average. The drinks don't take that long to come and still taste good. The staff is friendly enough and I haven't had a bad experience yet. They're polite and patient when take you're order (in my experience).
