There is always a long line here. That just goes to show how popular this place is! 👍 I came a bit late, so I didn't have to wait in line and was able to eat almost right away. Wow, it's a taste that Koreans are bound to love... It would be perfect for a hangover the day after drinking, too. The portions are really huge... It's a flavor that everyone is bound to enjoy, without any strong preferences. I hope they open more branches! 😉 This place always has a long line, which tells you how popular it is. 👍 I came just before closing time, so I didn’t have to wait in line and was able to start eating almost right away. The food would be perfect for a hangover after a night of drinking, and the portions are huge. It’s the kind of food that almost everyone would enjoy—there’s really nothing to dislike. I hope they open more branches in the future! 😉

I used to patronize the elder couples who serve generous portion. But when I went today, the stall is managed by 4 young guys. I noticed the prices are adjusted up. Small serving is $6. Mid range $8. The big serving is $10. This more like Michelin pricing. I used to enjoy it as comfort food fir decent meal. But the pricing has gone up too much. I guess they included the high overhead into their pricing. Even the empty container they charge $0.50 for mid serving takeaway. If bigger serving, the empty container would be $1.00. It is over priced for open kopitiam. I guess I will only come here if my craving comes. Otherwise I would spare the effort on the walking journey for overpriced fish soup.

I have been patronising this stall for more than 2 years now. I know the shop has a couple of new staff but an advice for the skinny guy who is doing the cooking ( I know the 3 new guys take turns on different days to cook), please taste your soup before you give to customers, your soup is bland and tasteless. The chubbier guy is able to replicate the taste of the original owners though

To me, Ubi isn't just an industrial zone—it's a goldmine of hidden food gems. Craving fish soup, I did a quick search and stumbled upon Thai Seng Fish Soup. I ordered the Double Fish Soup and added the handmade fish roe prawn paste balls. Between the rich, flavorful broth, fresh fish, and generous cilantro, every spoonful was pure comfort despite the Sun outside and the heat. A truly hearty meal, and I will definitely visit again very soon.

Terrible service. 1) They gave me fish soup without any fish slices!! 2) I asked for no coriander which still came with a whole bunch of it. 3) Took away fish soup with beehoon but they didn't offer separate packing for beehoon. Cancelled the beehoon and kept just they didn't refund my $1. 4) Rice was undercooked! 5) Cook felt like a disgruntled worker, miscommunication happening within their few staff Wouldn't come back again.

Soup was quite nice. Went at 1.30pm, about 3 people in queue. Fried fish had the standard alkaline taste. Sliced fish was good. Portion was huge, plentiful cabbage. Coffee shop had alot of crows and pigeons on standby to unsuspecting patrons.
