The perpetual line out front is a testament to this restaurant’s reputation as the place to get the city’s best pho. Do what the regulars do: Order the No. 1 dac biet, known for its ultra-smooth, aromatic broth, ask for the tender marinated beef (tai uop) on the side, and dump it into your steaming hot soup to cook. Upgrade to nam cuc beef brisket cubes for even more enjoyment.
