Tonkin Specialty Coffee is a coffee shop on the third floor of a narrow alley in Ho Chi Minh, and it focuses on egg coffee. The signature egg coffee is drunk by mixing fluffy egg cream with the coffee to taste, and milk coffee and salt coffee can also be ordered. You go up to the third floor through the narrow alley and stairs, and the shop has air conditioning. The shop is small and drinks take a long time to come out after ordering.
