Gong cha is a specialist in bubble tea (boba) and milk teas of Taiwanese origin. The drinks rest on freshly brewed loose-leaf tea, and the customer customizes each cup — the level of sugar, ice, and toppings like tapioca pearls, jelly, pudding, or milk foam. The menu spans brewed teas, milk teas, signature specials, smoothies, and coffee, so it offers hundreds of combinations rather than the simple coffee lineup of an ordinary café.
