I've been here at least twice, and both times consistently 'meh'. The buns were fine, but the bubble tea was way too sweet. I asked if it was possible to get black tea in my mango flavored bubble tea (which, as one would expect, often contains actual TEA), and the person working there snidely replied "Umm no, we don't put tea in juice" as if I was making an unreasonable request. So basically they don't serve bubble tea, they serve juice, according to their staff.
Also, questions regarding sanitation. I asked someone working there where I could find some tongs, and she pointed to a pile of dirty one grouped together on a counter. Those were the only tongs available.
My suggestion: go to Harmonie or L2 for real (and good) bubble tea, and Harmonie has great pastries without the attitude. Not sure what the point of being rude is when you have so much competition 2 doorstops away! It just pisses people off and makes their dining experience unpleasant. Why would you want your restaurant to be associated with that? Won't be going back.
