Bun Thang

Bun Thang is a signature Hanoi noodle soup distinguished by clear savoury broth, fine rice vermicelli and carefully cut toppings.

Overview

Bun Thang expresses a refined side of Hanoi cooking. Fine bún, shredded chicken, giò lụa and thin omelette strips are coordinated with clear hot broth. Official tourism material links the dish with creative use of foods remaining after Tết, but this profile treats that as cultural narrative rather than a proven single origin event.
