Reviews
KOI bubble tea outlets across Singapore regularly deliver well-loved drinks with chewy pearls and strong tea flavors, but experience varies by location. While many customers praise fast service and friendly staff, a large number of reviews highlight long waiting times, disorganized queues, understaffing during peak periods, and occasional rude or inattentive service. Some outlets struggle with app or kiosk ordering, missing card payments, and occasional stock issues with pearls, leading to frustration even as the core product remains reliable and enjoyable for most patrons.
