Cafe Đen Đá is a 24-hour cafe in District 1, Ho Chi Minh City, near the rear gate of a church. It serves Vietnamese coffee and brunch, including bottled cold brew, cà phê sữa đá, and cinnamon caramel croffles. Many customers sit on the red bathtub chair at the entrance and drink by the roadside. The second floor draws many local students, and seats are hard to find even late at night.
