Our take: 21 Seafood appears to be a solid neighbourhood zi char spot, particularly lauded for its crab dishes.
Reviewers consistently highlight the freshness of the crabs and the value for money, with offers like 3 small crabs for $55 or 2 larger ones for $50 being frequently mentioned.
The Chilli Crab sauce receives praise for its flavour, and pairing it with mantou buns (5 for $2) is a popular recommendation.
While the crabs are a clear draw, other dishes like the chicken with dried chilli and hot plate tofu also get positive mentions.
However, the oyster omelette seems to be a miss for some, with a strong aftertaste.
We think it's a strong contender for those seeking affordable and fresh seafood, especially if you're in the Hougang area.
The lack of GST and service charge further enhances its value proposition.
Best for groups looking to share multiple dishes.

What customers say
21 Seafood is highly regarded for its fresh and well-prepared crabs, particularly the chilli and black pepper varieties, often highlighted for their good value and generous portions, especially the 3-crab for S$55 offer.
While crabs are a consistent hit, other dishes like salted egg squid, cereal prawns, and hot plate tofu also receive praise.
However, some dishes like the oyster omelette and prawn paste chicken are considered less impressive, and occasional issues with crab cleaning are noted.

Our all time favorite, the buttered crab with mantou.. This place is such memorable place for us every time we have occasions or visitors. We also love their Cereal Prawns and Slated egg squid.
The crab was well cooked and the way they crack the crab makes eating easy Worth travelling so far to eat. It was so nice we order another dish of salted egg crab .
The food was excellent. The prices for it was ok for 3 people and a table of high quality food. The crab was especially great but the prawn paste chicken felt like frozen chicken and felt a bit basic.…
