Mellben Seafood started off from a stall at commonwealth avenue in 1979 to one of the argued best places for chill crab in Singapore. The well-known Chill Crab is served with the thick and eggy chill crab gravy. The taste is well balanced between sweetness and spiciness, which can be dipped in Mantou to experience the savoury sauce. The crabs are served fresh, which is served fleshy and sweet with the dedicated efforts to ensure its freshness and taste.

There were also other crab-related dishes offered, such as Black Pepper Crab, Butter Crab, Curry Sauce Crab, Salted Egg Yolk Crab, Shimmering Sands Crab, and Claypot Vermicelli Soup and Laksa Crab.
