In terms of actual bubble tea, I find their drinks to be watered down compared to Chatime. I always get less ice and significantly less sugar in any bubble tea place. Both their house milk tea and oolong tea didn't have a strong enough tea flavor in it, leaving me disappointed. Their house green milk tea, however, is decent. In terms of food, the parmesan basil fries are definitely good, yet very soaked in oil and a bit too salty.
Tl;dr - I definitely prefer Chatime due to their stronger tea. Come to Latea if you want their snacks or a more "open lounge" atmosphere.
