Since day one, this place has only ever served one thing – the zhajiangmian, for which diners come in droves, from opening until closing time. These delicious, chewy noodles are dressed in an aromatic soybean sauce that is slow-cooked for hours with diced half-fatty pork to develop depth. They are then topped with condiments such as shredded cucumber, radish and leafy greens. Feel free to garnish with pickled garlic and cumin chilli sauce for an extra kick.
