Gong Gong, commonly known as sea snails, is a type of shellfish that is quite popular in Singapore hawkers and Zi Char restaurants. This seafood packs a lot of protein, which is one of the reasons why it is a popular choice. It is certainly not on my Christmas card list though. The last time I saw something like this, Sigourney Weaver was trying to shoot it on a spaceship. Hence, I view it as hardcore.
Gong Gong, also known as the Pearl Dog Conch Sea Snails, is one of the most unique shellfish and one of the Southeast Asian favourites, hence you see it everywhere in Singapore.
