Duyen Beo is a local restaurant in an alley beside the Hanoi train tracks, serving seafood pho, bun cha, and stir-fried noodles. The seafood pho has a mild broth with mantis shrimp, and diners also order nem and beef stir-fried noodles. Orders with several dishes arrive late, with waits of fifty minutes to an hour. The bun cha is strongly sweet, so dishes vary from one to another.
