I usually get my drinks here. It’s supposed to be automated which makes things faster but there is always a line which is sort of puzzling. I got the chrysanthemum iced tea and it was quite sweet even with zero sugar with a herbal aftertaste. I also asked for aiyu jelly and the jelly was on point. The only annoying thing is the constant queue here

bought a drink today 12 july around 7:30pm and shared it with my sister. she was finishing up the drink and chewing on the pearls when she found a fingernail inside her mouth. this is really disgusting and extremely unhygienic i have no idea how a fingernail could ever get in a drink or why anyone would even be cutting their nails while working in a drink store. please manage your employees cleanliness better.

Came at around 10.30am and waited for quite some time before I received my drinks. Got the Peanut Butter Milk Tea with Taro Q, 50%. The sugar level was just nice. It wasn't too sweet. The chunky peanut butter added a good crunch and flavour to the drink. The taro also complemented the drink really well. Overall I enjoyed the drink! Just hope that service would be faster. But maybe because I came too early so it was slower.

Visited on 5 April 2025 at 9:20 PM. There was already a queue, but we patiently waited to order at the kiosk. Unfortunately, the machine was extremely slow and laggy, making the ordering process unnecessarily long. After completing one transaction, the machine completely jammed when we tried to place another order. When I informed the staff about the issue, their response was impatient and rude. There was no attempt to resolve the problem or apologize for the inconvenience—just dismissive behavior. While I understand technical issues happen, it’s unacceptable for staff to treat customers poorly for problems beyond their control. A little courtesy and a willingness to help would’ve made a big difference. Very disappointed with the service.

After placing the order, I waited for half hour.When I went to pick it up, I was informed that I hadn't paid successfully. Why didn't you tell me earlier? I waited for such a long time without being informed! The staff service attitude is really bad!
Ella
Honestly the drink is so unappetizing. Like the photos in the machine is very misleading like why isit green if its not even green. Taste so bad like really bad its so bland like honestly send help. But overall the staff is nice just the drink is so bad i do not recommend buying green tea latte.....
Monica
I bought a green tea latte and the drink was not green at all. There was no taste of green tea and it tasted just milk with sugar. Will not recommend.

context: koi was crowded and the one and only machine had a snaking long queue. i wanted to use my voucher (hence needing the counter/machine assistance) i also wanted to top up my card with cash and a friendly worker 1 assisted me with it however when another worker 2 (wearing long black sleeve) saw that worker 1 was helping me, he said “it is not right for them to come to the counter to order and they should have queued up at the machine” right infront of me. i feel that this very rude and action should be taken against him. i just wanted to top up my card with cash and order my drink at the counter at the same time. cause it would be not be logical for me to queue up for the machine again just to order my drink after topping up my card when i could just order my drink at the counter. ( context: i did indeed asked worker 1 if i could order at the counter and he agreed)

Staff prioritises grab/mobile delivery order over people who order manually. It would be better if there's clear distinction one staff settle mobile order the other settle manual order. Like the ones who ordered waited 40 mins for a cup ;-;

Staff prioritises grab/mobile delivery orders over people who order manually. It would be better if there were a clear distinction: one staff member for mobile orders, the other for manual orders. For example, some customers waited 40 minutes for a cup.

Koi was crowded, and the one and only machine had a long, snaking queue. I wanted to use my voucher, which required counter or machine assistance. I also wanted to top up my card with cash. A friendly Worker 1 assisted me with this. However, when another worker (Worker 2, wearing a long black sleeve) saw Worker 1 helping me, he said, “It is not right for them to come to the counter to order, and they should have queued up at the machine,” right in front of me. I feel that this was very rude, and action should be taken against him. I just wanted to top up my card with cash and order my drink at the counter at the same time. It would not be logical for me to queue up for the machine again just to order my drink after topping up my card, when I could just order it at the counter. (Context: I did indeed ask Worker 1 if I could order at the counter, and he agreed.)

The staff was not polite. Why must you order using a kiosk when you want to pay cash or by ShopBack Pay? Why not let people using cashless payment use the kiosk instead? It was crowded, and a lot of people were queuing. I just can't understand it.

I arrived at around 10:30 AM and waited for quite some time before receiving my drinks. I ordered the Peanut Butter Milk Tea with Taro Q (50% sugar). The sugar level was just right, not too sweet. The chunky peanut butter added a good crunch and flavour to the drink. The taro also complemented the drink really well. Overall, I enjoyed the drink! I just hope the service could be faster. However, perhaps it was because I came too early, which made it slower.
