Dive into the secret world of the Biet Dong Sai Gon, the elite urban guerrilla force of the Vietnam War. Our journey begins at a quiet home in a 3 Thang 2 Street alley, once the clandestine weapons depot of Mr. Do Van Can. Here, a shoemaker-turned-commando built a hidden underground bunker beneath his living room sofa to store explosives smuggled from An Dong Market for the historic Tet Offensive. Next, we visit Pho Binh on Ly Chinh Thang Street. Over traditional northern-style pho, learn how 100+ commandos assembled here in January 1968 to receive final orders for the U.S. Embassy attacks, and meet a living eyewitness of those pivotal days. We then explore the Saigon–Gia Dinh Special Forces Museum, packed with rare artifacts of those who fought from the shadows. Conclude at Do Phu Cafe, where a simple wardrobe conceals a hidden hatch leading to a wartime shelter. An unforgettable look at Saigon's hidden history.
