I went to ChaTime during their opening weekend. I've never had ChaTime before but I heard good things. There was a good BOGO deal that I couldn't resist- I paid about $5 for two drinks.
There was a long line but hopefully that was only because of the grand opening related coupons that everyone was using.
I had the QQ mango drink- it was pretty good. My girlfriend had the Jasmine green tea with tapioca and she liked that she could customize how much sugar and ice that you could put in- kind of like Starbucks for Bubble Tea.
The tea seemed like it was made of fresh ingredients and the price was decent (even without the promo).
Definitely will be a repeat customer whenever I'm in the area.
