In a city known for specialty coffee, third wave roasters, and tech driven food trends, one of San Francisco’s hottest coffee experiences involves plastic stools, slow dripping coffee filters, and a distinctly Vietnamese approach to taking things slow.
Every weekend, crowds gather in the city’s Mission District, patiently waiting up to an hour for a cup of Vietnamese coffee from Nâu Coffee, a mobile pop up founded by two young Vietnamese entrepreneurs who have recreated the atmosphere of a traditional Ho Chi Minh City sidewalk café thousands of miles from home.
What began as a nostalgia driven passion project has quickly evolved into one of the Bay Area’s most talked about food experiences, attracting everyone from curious locals and coffee enthusiasts to members of California’s Vietnamese diaspora.
The concept was created by Hiểu Hân, 27, and Trung Kiên, 25, both originally from Ho Chi Minh City and now living in the United States. The idea emerged after Kiên returned to Vietnam in 2025 and rediscovered something he felt was missing from American coffee culture: the ritual of sitting patiently and watching coffee slowly drip through a metal filter.

Instead of adapting Vietnamese coffee to local tastes, the founders chose authenticity.
Their robusta beans are sourced directly from Buôn Ma Thuột, Vietnam’s coffee capital. Condensed milk, traditional metal filters, and even the iconic low red plastic stools synonymous with Vietnamese street cafés are imported from Vietnam despite the additional cost.
For the founders, the stools are not merely furniture. They are part of the experience.
“It’s difficult to recreate the atmosphere of a Vietnamese sidewalk café without them,” Hân explained.

That commitment to authenticity appears to be resonating with customers.
Since launching its first pop up in 2025, Nâu Coffee has expanded across multiple locations around the San Francisco Bay Area. Today, each event typically serves nearly 400 drinks during a four hour opening window.
The menu features Vietnamese classics including iced milk coffee, salt coffee, egg coffee, and pandan coffee, with drinks priced at approximately $7 each.
The concept gained wider recognition after being featured by food publication Eater, which described customers waiting for hours to try Nâu’s signature salt coffee, a Vietnamese specialty topped with a lightly salted cream layer. Local television station KRON4 also spotlighted the business during Lunar New Year celebrations earlier this year.
Yet the long lines are not simply about coffee.
For many visitors, the attraction lies in the experience itself.
Unlike espresso based drinks prepared in seconds, Vietnamese filter coffee requires patience. Customers often watch the brewing process unfold slowly while sitting outdoors, chatting with strangers and soaking in an atmosphere rarely found in modern American coffee shops.
Many first time visitors find themselves asking questions that go beyond the menu.
Why are the stools so low? Why do Vietnamese cafés spill onto sidewalks? What makes robusta different from arabica? Why does the coffee taste so strong?
Rather than offering formal explanations, the founders prefer letting visitors discover the answers through experience.
“We’re not trying to teach culture through lectures,” Hân said. “We want people to feel it for themselves.”
The approach reflects a broader shift in how Americans engage with international cuisines. Increasingly, diners are seeking cultural experiences rather than simply consuming foreign foods.
For Vietnamese Americans, the pop ups offer something even more personal.
Some visitors drive for hours just to spend an afternoon sitting on familiar plastic stools, hearing Vietnamese conversations, and enjoying a style of coffee that reminds them of home.
One customer reportedly traveled two hours from Santa Cruz after seeing videos of the pop up on TikTok.
“It’s not just about the coffee,” he said. “It’s about reconnecting with memories.”
Operating the business remains challenging. California’s regulations surrounding outdoor food service make permanent sidewalk operations difficult, forcing Nâu Coffee to partner with restaurants and bars that can provide temporary outdoor spaces.
The founders currently rotate among multiple locations and continue balancing the project with full time careers in consulting, finance, and technology.
Their long term goal, however, is clear: opening a permanent café in San Francisco.
Beyond coffee, they hope to introduce more everyday Vietnamese drinks such as sugarcane juice, pennywort juice, and fruit teas, while collaborating with other Vietnamese and Vietnamese American entrepreneurs to create a broader cultural hub.
For now, Nâu Coffee’s success suggests that American consumers are increasingly eager to explore deeper layers of Vietnamese culture.
Phở and bánh mì may have introduced Vietnam to many international diners. But in San Francisco, a simple plastic stool and a slowly dripping coffee filter are showing that some of the country’s most meaningful cultural exports are also its most ordinary.
