Mama Dung started out in the northern city of Nam Dinh in 1986, armed with her grandmother's recipe for a light, clean, pure broth. Now, in this shop, diners choose between a three-day beef-bone stock or chicken broth; stand-out dishes include the phở bắp hoa, featuring crunchy medium-rare beef, and Mama Dung's gà tôm mắm sốt (crispy fried chicken). There is also phở tine – a creative Western-style take on phở, served with golden French fries, beef noodle soup and cheese.
