This bubble tea chain is from Taiwan and the quality is considered to be very good in NY. Their summer special for the mango slushy (芒果冰沙) is the best in NYC. I believe they use fresh mango!
Best bubble tea in Manhattan, hands down. Good pearls, good mixes, fully customizable drinks (sugar, flavor, add-ins, etc) and good hours. Service can be slow.
This place is great! I recommend the passion fruit green tea with bubbles and coconut jelly. Watching their machine cap your drink is beyond satisfying.
