Oyster Vermicelli

No night market worth the name is without this unassuming little treat. The quality of this dish is judged by the freshness of the oysters and the chewiness of the noodles. The dish is made with a type of red vermicelli noodle that does not crumble easily. The noodles are served in a soup stock with fresh oysters and soy-stewed large intestines, and flavored with black vinegar, a special sauce, and a garnish of cilantro.
