You can buy a wide assortment of juices and teas throughout the streets of Taipei and Taiwan. Their menus often resemble stock listings in sheer density of information. In addition to the kind of juice or tea that you wish to purchase, Taiwanese and savvy foreigners can supplement their order with a range of custom options. Rarely are these “documented” options but at least one juice vendor chain shows you some of the options at your disposal:
Here you can see that it is possible to customize the amount of sugar and the amount of ice which is added to your drink. You can get everything from “full sugar” (100% the normal amount added) to “no sugar” and everything from the normal amount of ice to no ice. You can also order your drink warm or hot.
I like to order lemonade or a mixture of lemonade and mandarin orange with “half sugar” (半糖） and not much ice （少冰).
