One Prawn & Co is praised for bold, seafood-focused cooking, open-kitchen theater, and attentive service. The prawn toast, jumbo tiger prawns, and 16-day dry-aged kingfish are consistently highlighted as standout dishes, along with smoky hor fun and prawn ramen broths. The setting and staff are repeatedly described as welcoming and stylish, making it a good venue for dates or celebrations, especially on set menus. Some reviews flag high prices, small portions, and occasional service issues or heavy, oily or sweet broths. Overall, it’s regarded as creative and rewarding for seafood lovers despite price and consistency caveats.
