Finally tried limited edition drink for Biscuit Milk Tea ($4.90) from KOI. Ok I felt that it tasted like ovaltine tbh after a few sips. My sister she asked me to redeem and try free drink from KOI lol so I decided to write drink review for it. For the size of the drink, I felt it was quite small size compared to normal drink and the biscuit shaves topping were quite enough for covering up the drink. I would not buying the drink directly without the card deal ($22) tbh as probably the size of drink didn't marked up for price.
