YaYa Tea Garden for their rice balls. Medium (not large- too much rice) Shrimp Tempura is the best. And ANY of their Fruity Bubble Teas! I like their original hole in the wall location on Chrystie Street. https://www.yelp.com/biz/yaya-tea-garden-new-york-3?osq=yaya
Their newer, bigger location on Grand Street has a Shake Shack vibe to it, which is not bad, it's just not "YaYa". https://www.yelp.com/biz/yaya-tea-garden-new-york-6?osq=yaya
