Founder Steven Tan told The Straits Times the Singapore outlet is slated to open at the end of September.
CapitaLand, which manages Funan, also announced the move on its website, though it did not provide a specific date.
Since opening its first shop in Kuala Lumpur's Taman Cheras neighborhood in 2022, Hai Kah Lang has expanded to eight outlets across Malaysia, including Johor Bahru and Kuala Lumpur International Airport Terminal 2, Malay Mail reported.
Its flagship outlet has received the Michelin Bib Gourmand award for three consecutive years, from 2023 to 2025. The Bib Gourmand is given to restaurants that offer the best "value for money," according to the Michelin Guide.
The restaurant's menu features prawn noodles, crab meat porridge, and fish head noodles, alongside snacks such as Teochew oyster omelettes, stir-fried fish lips, and fried soft-shell crab.
Hai Kah Lang's arrival comes as Singapore's dining scene has been struggling with rising costs and the closure of several iconic restaurants in 2025.
But Tan remains optimistic.
"We are confident our offerings will resonate with this great nation of food lovers," he said.
