Koi Thé @ Ubi

KOI reviews consistently flag inconsistent app status and order tracking, frequent delays, and variable service quality, especially at Hillion Mall. While some staff are praised for friendliness and drinks taste good when served, many customers report slow preparation, misrepresented readiness, rude attitudes, and unreliable displays. Positive notes highlight efficient staff and pleasant experiences when operations run smoothly; overall, customers advise caution during peak times and in outlets with reported system issues.
