Bún chả 22 ngõ Huyện is a local bún chả stall in an alley near St. Joseph's Cathedral in Hoàn Kiếm, Hà Nội. Diners sit on small stools in the alley and eat charcoal-grilled pork dipped in a sweet-and-salty nước mắm sauce, served with light, chewy noodles and herbs and vegetables. The stall opens early in the morning and closes in the afternoon. The portions of bún chả are large.
