Coffee A is a two-floor cafe near the Hanoi Old Quarter night market, serving salt coffee, egg coffee, and banh mi. The egg coffee is sweet like cream with a bitter finish, and salt coffee is also available. From the second-floor terrace, you can look down at the intersection and the yellow building across the street, while the indoor seating is cool with ample space between tables. The terrace is noisy and uncomfortable because of smoking at nearby seats, and the restroom is very small.
