Went with another new drink at Yuan Cha and we were told they use freshly squeezed lemon juice in this, and thus they pre-warned us on how sour it would be. We still went ahead with 25% sugar when we should have really just listened to the experts and gone for more HAHAHA. The lemon juice kinda overwhelmed the green tea, but the sweetness of the coconut jelly helped to cut the sourness quite a bit. Not my favourite drink here but I may try it again at 50% or 75% in future just to see the difference!
