David Chang opens Momofuku Noodle Bar in New York City’s East Village (171 1st Ave). The restaurant’s steamed bun program—especially the now-iconic pork belly bun—helped make modern, remix-driven Asian-American flavors mainstream and provided a template many later “bao crossover” concepts built on.
Momofuku Ssäm Bar opens in New York, strengthening the broader cultural visibility of steamed buns (and bun-like sandwiches) within a fast-moving, late-night small-plates scene—an important on-ramp for later nontraditional fillings and crossovers in “bao” formats.
Kogi Korean BBQ begins operating in Los Angeles, popularizing Korean–Mexican street-food hybrids (tacos, quesadillas, sliders). While not a bao concept, Kogi’s viral, remix-forward model accelerated demand for portable “global mashups,” creating fertile ground for bun-and-bao crossovers that followed in the 2010s.
Eddie Huang opens the original Baohaus on the Lower East Side. The shop helped cement “bao” (often used in the U.S. as shorthand for gua bao-style folded buns and other bun sandwiches) as a modern, customizable platform for varied proteins and flavor profiles.
In London, BAO starts as a street-food project (including a stall/shack phase associated with Netil Market). Its Taiwanese-inspired buns helped normalize “bao” as a standalone, mix-and-match format in the UK and Europe—setting the stage for later mashups like bao burgers and dessert baos.
BAO opens its first bricks-and-mortar restaurant on Lexington Street in Soho. The move from stall culture to a high-demand restaurant brand signaled that modern “bao” could anchor a full-service concept—and supported later experimentation with sweet/savory and cross-cultural fillings.
BAO opens its Fitzrovia location, reinforcing the brand’s influence and helping “bao” become a recognizable, repeatable format across neighborhoods—an important step in globalizing bao-adjacent hybrids beyond one-off pop-ups.
UK supermarket Sainsbury’s launches bao buns in its “on the go” range, reflecting how the bun format was moving from restaurants into mass retail. Retail availability made it easier for cooks and small operators to build “steam-bun crossovers” without in-house bun production.
Bao Bao starts selling handmade steamed bao from a downtown Portland cart (10th & Alder). Food-cart ecosystems like Portland’s helped spread bao experimentation—often with locally inspired fillings and menu pairings—outside major coastal dining hubs.
Black Seed Bagels and Nom Wah Kuai introduce the “Baogel,” explicitly hybridizing a bagel with char siu bao-inspired form and filling. It became a highly legible example of bao hybridization: not just new fillings, but a re-engineered starch platform that blended iconic breads.
BAO opens at Borough Market, continuing its multi-site growth and reinforcing bao’s place as a widely recognized dining format in London. Expansion into a landmark food destination helped anchor bao’s visibility for tourists and trend diffusion.
After operating as a cart, Bao Bao opens its first restaurant space in inner Northeast Portland. The shift from cart to restaurant illustrates how bao concepts matured into scalable local brands, supporting broader menu experimentation and sustained demand for bun-based mashups.
