I've recently added this place to my ever growing list of bbt to-go places and I can't say I've had a bad experience yet.
Drinks: So far I've tried their milk tea with various toppings including sago, pearls, pudding and grass jelly. I enjoy the stronger tea flavour in their milk tea though it can be sweeter than other places I've tried. In order to cut the sweetness, I usually get 30% or no sugar depending on the toppings. Definitely get no sugar with sago as the sago is soaked in sugar to begin with. Small tip, if you want to keep the strong tea flavour, get no ice.
Try the bbt here with less sugar and you won't regret it!
