The only pity about Coco's is that it's not all over the world (Okay, fine, there's 5 in NYC and 2 in LA). Other than that, it's perfect. You can order an assortment of bubble teas with tapioca, jelly, pudding, and many other options. Along with bubble tea, Coco's also serves the equivalent of Starbuck's "frappuccino" in flavors such as green tea or mocha.
I tagged this Coco's at a location I would frequent often, but Coco's is widespread throughout all of China (but found mostly in big cities) and all over Shanghai.
