I would recommend their pre-mixed Chaoniu dipping sauce which complements the tender beef excellently.
The owner is very passionate about the food and has done a lot of work to meticulously source the beef but most impressive is his insistence on pounding the beef by hand to make beef balls!
Overall, it was nice to found Teochew Beef Hotpot in Singapore. For those who never been to Shantou, this will be a good experience.
