"Thuy Nguyen’s cafe on Old Kent Road does serve oustanding Hanoi pho of clarity and depth; it does serve crackling rare beef salads and fried duck tongues. But its crowning glory — only available from the Vietnamese-only blackboard as a special — is its offal platter, boiled or fried, with blood sausage and intestines aplenty ready to be dipped into mam tom, the concrete-grey shrimp paste whose colour belies its intensity." - Jonathan Hatchman
