This place looks awesome, and I don't just mean the outside. It's a full on Chinese sweet treats and drinks emporium. Boba teas, soya bean cups, shaved ices, I've never had or even actually know what these things are but i'm going back to try some next time I'm down...
Bubble Tea (Boba tea) are large tapioca pearls that are added to the drinks. You get these large straw to drink up the tapiocas. I prefer the milk based drinks myself.
