This year, at least five businesses have opened or been announced along Union Street in Cow Hollow and just off the corridor. That is not unusual for a commercial corridor in San Francisco. What stands out is that most of these arrivals bring experience from elsewhere; Andon Market brings a new concept. Taken together, the mix offers a glimpse of how businesses are approaching this corner of the city.
Start with the most established name on the list, even though it sits a block over on Fillmore rather than Union itself. Turtle Tower, the Hanoi-style pho restaurant that built its reputation over two decades in the Tenderloin before closing in 2023, staged a comeback downtown at 220 California Street and then, once that reopening proved itself, brought a second San Francisco location to 3145 Fillmore Street in Cow Hollow earlier this year. Managing partner Arash Ghanadan told SFGATE the neighborhood offered strong foot traffic and a mix of locals and visitors who value a legacy brand with history. Notice what that is not: it is not a bet on an unproven concept. It is a business that already knew it worked, choosing a second stage.
The pattern holds all the way down the block. Breakfast Little, the breakfast burrito specialist that built a loyal following on 22nd Street in the Mission before moving to a larger space there in 2023, is now taking over 2223 Union Street, the former home of French bistro Gamine, according to the San Francisco Chronicle. Owner Andrew Martinez-Perez did not have to build an audience from scratch on Union Street. He is importing one that already exists three neighborhoods away.
Then there is Franko & Friends, which is not from San Francisco at all. It is the San Francisco expansion of Franko & Co., a Ukrainian-owned coffee shop already running in Sausalito, and it is set to debut at 2055B Union Street with owner Iryna Nevozhai targeting an early September opening, per WhatNow. Nevozhai has said the owners found that the area draws local residents with ties back to Sausalito, which is a specific and slightly unusual reason to cross the bridge.
The math behind a fitness chain's third location
The clearest version of this pattern is not a restaurant at all. The Yard Strength Training, a reservation-based gym built around private squat rack pods, signed a 4,300-square-foot lease at 1906 Union Street in June, with an opening targeted for September. This is the company's third Bay Area location, and founder Joseph Cicero was explicit about why Cow Hollow made the list.
"Cow Hollow sits squarely between the two communities we already serve heavily," Cicero said, describing consistent demand from members and trainers for more access in the corridor.
That makes Cow Hollow an extension of an existing service area, rather than a new market for the company. Union Street is not where The Yard is testing an idea. It is where The Yard is closing a loop.
A new concept on the corridor
Andon Market, the retail boutique at Union and Webster, brings a new concept to the corridor and made news this spring for an unusual reason: it was designed, stocked, and staffed almost entirely by an AI agent. The startup behind it, Andon Labs, gave an AI system built on Anthropic's Claude a corporate card and a budget under $100,000 and let it make the calls on logo, merchandising, interior design, and hiring, as SFist reported in April.
On its surface, this is the one truly original concept to land on the block this year. Andon Market is at Union and Webster, a corner with decades of established foot traffic and a shopping habit already baked into the neighborhood's rhythm. Its location puts the new concept on the same established corridor as the other arrivals.
Why Union Street already draws an audience
One feature of Union Street that may appeal to operators is its established foot traffic, and the roots of that draw predate every business on this list by decades. The Union Street Festival, produced by Sunset Mercantile in partnership with the Union Street Association, has run along this stretch since 1976. The 2026 edition took place the first weekend of June between Gough and Fillmore, drawing food trucks, live music, and the neighborhood's long-running Waiter Relay Race, an event where restaurant and bar staff race uphill balancing trays of drinks. Fifty years of that kind of programming does not just fill a weekend. It trains a habit into the people who live nearby, so that Union Street stays a place worth walking even on an ordinary Tuesday.
That habit may be one feature of the corridor that appeals to operators. A gym chain can benefit from a corridor that already delivers people who walk it regularly. A Mission burrito shop can benefit from a block with a track record of supporting food-forward small businesses. Even a Sausalito coffee shop can bet on Union Street specifically because its owners noticed the neighborhood already has ties to their existing customer base.
What this means if you already live here
If you have walked past 2223 Union Street or 1906 Union Street recently and wondered what is going in, the honest answer is that you are watching operators do their homework before they open, not after. Most of the businesses on this list bring concepts proven elsewhere. Andon Market brings a new concept to the corridor.
There is a flip side worth sitting with. Several of the businesses announced for Union Street bring concepts developed elsewhere, while Andon Market represents a different kind of experiment. The announcements reflect both familiar formats and a new approach. For residents, they point to a range of businesses with different kinds of experience behind them.
Either way, the next time a storefront on Union Street changes hands, it is worth asking not just what is moving in, but where it has already proven it works. On this block in 2026, that question has an answer more often than not.
