Fresh apple and sea coconut drink @ Kung Wo Tong

Saw the poster and the drink looked refreshing so I tried it.

 

I thought it was a hot drink but it was chilled.
Anyway the drink was apple and sea coconut.

 

There was apple juice in it but it was not sour and the sea coconut tasted nice as well because it was not sweet at all.
However it was slightly strange because it tasted milky.
