The Queens Quay bubble tea drought is over!
I visited during the grand opening promotions where they gave out free large sized drinks. I got the Okinawa Milk Tea (normally ~$5), which used roasted brown sugar instead of white. Had a bit of a confusing moment when I asked for low sugar and the staff told me anything less than 80% wasn't possible, even though it was - no complaints though as this was all free. On a later visit the Classic Milk Tea was decent too - could be a bit stronger but I'm mainly happy there's a tea shop in the area.
TIP: this takeout spot is small so there are only a few counter seats.
