Terra Café & Workshops is a café on the fourth floor near Hoàn Kiếm Lake in Hanoi's French Quarter, serving coffee and pastries. It offers salt coffee, coffee topped with thick milk foam, and house-made liquor. Indoor and terrace seating make it suitable for studying or working on a laptop, and a white cat lives there. The sign and entrance outside the building are small, which makes it hard to find on a first visit.
