Cafe Muối is a cafe on the first and second floors of a building at the corner of Giang Văn Minh Street and alley 42 in Ba Đình, Hanoi, serving salt coffee, tea, and smoothies. Its signature salt coffee combines strong coffee with salty and sweet flavors, and an avocado salt coffee is also available. The space is large and clean and spans two floors. The salt coffee tends toward sweetness, so it is better to ask for a lower sugar level when ordering.
