The service attitude is really average. You just order a drink, pay, and leave. You don't need to ask for too much or expect too much. However, black tea is highly recommended. In the first portion, except for Li Ji and Ah Bing, Shiwai’s black tea has the strongest ancient flavor, and it may also have the strongest cassia seed aroma among the three. It also has a special aroma unique to their family. However, the ice cubes in the drink are crushed ice. I personally don’t like it very much. I drink it. It feels like the crushed ice has absorbed all the tea soup. It's gone after just one sip. It's the same as the tea soup. It tastes good but I don't like crushed ice. However, the black tea is still quite strong. If you like the ancient taste, don't miss it.
