This is the only Herbal Tea stall that I like. Auntie sells a total of two type of Herbal Tea. Bitter and Sweet. I can only take the sweet one. Natural sweetener is added for health purpose. Sweetness is just the right amount and no taste of bitter herbal tea. As for the bitter one, my advise is you need to have some courage to try. It cost $ 1 more than the sweet one probably become of the additional chinese herbs added. The one and last chance I had trying the bitter one was cause someone told me bitter one if more effective. I choked on the first mouth due to the very very very bitter taste. And for some time, the taste just doesn’t leave your mouth. That is when I deduct by my own logic that Herbal tea no matter sweet or bitter, the effect is the same. The bitter herbal tea was also use to play this game of drinking without changing your expression. I always lose making the ugliest face expression. But boyfriend doesn’t stop amuse me when there wasn’t a slight change in his expression. I will still get from this stall everytime I am at Old Airport Road.
