There's a few Presotea in Pacific Mall so don't fret if one has too long of a line! They do sometimes have a wait! I've gotten the grass jelly milk tea, the burnt Japanese Coffee, strawberry banana smoothie, brown sugar milk tea . . . all have been good! Go with 1/2 sugar since even that is plenty sweet! And make sure to tell them because if you even wait a half second to tell them to make it less sweet they'll say you should've told them earlier!
Anyways, pricey but delish!
