The sizes are small, large and extra large. When you order your drink there is no sugar or ice adjustments. I ordered the matcha tea latte and it's not as sweet as the original milk black tea. The matcha tea latter was a bit watery but the tapioca had a nice texture and was sweet. The original milk black tea was sweet and creamy which was nice so I would recommend the original more then the matcha. I ordered one matcha and two original but only two came. After a while I went up to the counter to ask where the third drink went and they said someone must have took it so they made our third drink fairly quickly and apologized. Overall it was a good experience.
