Once Taiwan is famous with its tea, so the colorful choices of tea are populous on the street. You could stop your foot when you pass through one the tea shop, even you do not really know what they taste, just try it next time when you are travelling in Taiwan .
People like to drink green tea,black tea or oloong tea here. Those are basically element to make the boobling tea. Then you could choose add milk, or purple (which is made of yam powder or rice powder mixed with black sugar),buting or other small snacks. As to me, i Like the green tea, plus lemon juice and mix with one bottle of Beer, totally mixed together, it is quite nice.
Just remeber, tell the waiter if you want free sugar, half sugar or full sugar, or you want cool tea without ice cube, or you want half ice/half hot..any preference you want, then just ask them to do .
The other traditional thing the visitor need to try is ice, with fresh fruits, or red beans, green bean, others i even do not how to describe in Enlgish, they are quite delicious and
yummy.
