Those little black tapioca balls might not have entirely caught on but maybe it's just because it's not done right at most of the places pouring out tasty fruity tealishy drinks. Ten Rens knows how to do it right with a good soft and chewy ball that's not at all mushy or hard at the same time. Love me some taro black milk tea these days. It's rich and somehow refreshing all at once with a nice mild bitter edge to balance the sweet.
