This Gong Cha's products are the closest tasting to the real thing I've had outside of Taiwan. I've been to all 3 locations in Northern California and they were crap, so I was very cautious about trying out this location.
The drinks really taste authentic, albeit slightly sweeter than I'm used to. The Black Forest drink is super sweet but addictive because its all desert toppings. You really should try it at least once.
I wish this place wasn't so expensive, because I've been going there everyday while I'm in town, but it keeps the wife happy so I guess its worth it. The service is random, sometimes its really slow, but as long as the drinks are consistently on point, I'm fine with it. Parking as so far been easy which is a rarity in a Chinese mall.
