Reached right when they opened hence pealrs were still not ready (i.e. couldn't order the brown sugar series drinks), hence I ordered the mango smoothie with lava ($5.8) and volcanic white sapphire ($4.8).
As for the volcanic white sapphire, it was the most ordered drink as seen from the IG photos. The coconut milk is mixed with Spirulina for the blue colour! (There is no added taste from the blue Spirulina) The drink comes with peach gum as well which is like jelly white fungus like texture.
Do check out the stall at city Square mall for these interesting drinks! They are located right opposite dondondonki.
Do note that their operating hours seem to start from 1130am now (instead of 10am as shown on Google map)!
