The tapioca pearls are not as good as at Chatime, the service is a little bit slower, but it is not as crowded, they use real fruits for several drinks (and not only powders or syrups like at Chatime... thus it takes longer to prepare) and you can mix everything you wish with anything you want... super great! Prices are grossly the same.
Thus, honestly, when I am in creative and experiencing mood, I'll go there... or if I wish for some quietness and larger place to sit and take a break...
Let's see if the place will stay open long or not... as Chatime is really attracting many more customers... but I'll be sad if this one closes... because it is also a very good option.
