Madam Ong Kim Hoi famously started out with an unnamed hawker stall (hence 'No Signboard'), but the popularity of her seafood made her a rich woman, with four restaurants and counting. Principally famous for its white-pepper crab, No Signboard also dishes up delightful lobster, abalone and less familiar dishes such as bullfrog.
Other Singapore branches are at Clarke Quay, Esplanade – Theatres on the Bay, and VivoCity.
