Originator of Vietnam's legendary egg coffee drink

"Down a narrow Old Quarter alley, the original purveyor of ca phe trung still whips up its secret egg-coffee recipe into a rich, frothy, almost dessert-like drink." - Scott Campbell

"Egg coffee (ca phe trung or cà phê trứng) emerges as a beacon of innovation amidst wartime scarcity. In the 1940s, as sugar and milk prices soared, Mr. Giang, the founder of Giang Cafe in Hanoi, turned to egg yolks, inspired by his experiences at the Metropole Hotel (presently Sofitel Legend Metropole Hanoi) and the allure of cappuccino." - Lana Tran

"Cafe Giang, named after Nguyen Van Giang, offers ca phe trung, a coffee drink he invented at Hotel Metropole by substituting eggs for milk, giving it a thick, eggnog-like texture." - MICHELIN Guide Thailand

"In Hanoi, Cà Phê Giảng (Giang Café) claims to have originated Vietnamese egg coffee in 1946 when founder Nguyen Van Giang, having run out of milk, improvised by using chicken egg yolk as a thickener; the recipe mixes egg yolk, coffee powder, condensed milk and optionally cheese, is often served inside a bowl of hot water, and—according to his son Nguyen Van Dao—the egg foams and enriches the coffee much as milk would. I also note a richer Vietnamese variation, sinh tố cà phê chuối bơ, which blends coffee and egg with banana and avocado into a smoothie-like drink." - Paolo Bicchieri
