If you have lived on Green or Filbert for more than a couple of years, you already know the rhythm of Union Street: the same florist on Fillmore, Balboa Café holding its 1913 interior together, Perry's at Laguna doing what Perry's has done since 1969. The surprise of summer 2026 is not that the corridor has changed. It is what direction it has changed in.
The opening class of the past twelve months is smaller in footprint, more specific in cuisine, and more clearly aimed at the person walking six blocks from home than at anyone Googling "best brunch in San Francisco." That is worth paying attention to, because at the exact same moment, a startup at Union and Webster is running an experiment to see whether a neighborhood retail block can be operated entirely by software.
The through-line
The blocks between Gough and Steiner used to trade in visibility. Storefronts wanted the tourist, the Marina spillover, the first-date crowd from across town. The recent openings are quieter than that. A Mediterranean bakery. A Vietnamese counter. A dumpling room. A single-flavor ice cream shop. None of them are trying to be a destination. They are trying to be someone's Tuesday.
Block by block: the openings worth walking to
Cheminé is the one that most obviously reads the room. It is a Mediterranean bakery and cafe with what The Infatuation politely describes as tons of space to spread out, free wifi, and, most importantly, chairs with backs. In a neighborhood where the coffee shops have historically been either grab-and-go or so packed at 10 a.m. that you cannot open a laptop, Cheminé has quietly become the mid-morning office for people who used to commute downtown. The baklava cheesecake and borek are the draw; the seating is the reason it will still be there in two years.
Dumpling Union opened as a solid Chinese restaurant with dumplings, noodle dishes, and more, and has slotted into the weeknight rotation for households that were previously ordering in from Chestnut. It serves the categories you'd expect — wontons, siu mai, steamed varieties, scallion pancakes, fried rice — without asking anyone to make a reservation two weeks out.
Turtle Tower brought its Cow Hollow location online serving the same excellent phở gà as the original. This is the kind of expansion that changes a neighborhood's default lunch, not its skyline.
Angela's Ice Cream is a small scoop shop with, per local reviewers, creative flavors. It replaces exactly the kind of storefront that used to churn through boutique concepts every eighteen months.
Roaming Goat at 1830 Union is the wine bar with the most specific point of view of the group. It leans into flavors and styles from the Mediterranean and beyond, highlighting unique selections from Armenia and Georgia, the birthplace of viniculture. Happy hour runs daily from 3 to 5, and weekend brunch is 11:30 to 3. A wine list built around Armenian and Georgian bottles is not something Union Street had a year ago.
Palm House is the one to know if you have a dog. Reviewers describe it as a Cow Hollow staple for dog-friendly meals, boozy slushies, and decent bar food. It has become the default patio for the 5 p.m. crowd walking home from the Presidio.
Mama's Luncheonette is a halal counter with an outsized reputation for one specific item: a chicken caesar wrap packed with lemon pepper chicken, croutons, and a wheel's worth of parmesan. If you have not tried it, this is your signal.
Blue Whale Restaurant & Lounge took the former Osha Thai space at 2033 Union and reopened as an Asian-fusion room with a full bar. It is currently one of only six restaurants OpenTable lists as bookable in the Cow Hollow slice, which is either a comment on how the algorithm defines the boundary or a comment on how many places here still operate on a walk-in basis.
And Motoring Coffee remains the outlier that everyone from out of town wants to see. It is part car showroom, part café, founded by Michael Rapetti as an enthusiast's club in Los Angeles, and the San Francisco location rotates vintage cars through the middle of the room while projecting Formula 1 on the wall. Locals treat it as a Saturday errand. Visitors treat it as a photo op. Both are correct.
The experiment at Union and Webster
Now for the counterweight. In April, a startup called Andon Labs opened what may be the most watched retail space on the corridor. The lab signed a three-year lease at Union and Webster and assigned an AI agent to create, stock, and staff a brick-and-mortar store on its own for under $100,000. The agent, named Luna, was developed using Anthropic's Claude Sonnet 4.6 to help detect errors that agents encounter while operating tasks in the real world.
The store is called Andon Market. The cofounders have already conceded some of what it revealed. "We helped her a bit in the initial setup, like signing the lease. And legal matters like permits and stuff, she sometimes struggled with," Petersson told Business Insider. Luna forgot to schedule a human worker for the store's opening day over the weekend but managed to contact its new employees and got one of them to come in at the last minute.
Whatever you think of the concept, it lands as a useful contrast. The other openings on this list succeed because someone is standing behind the counter who has met the regulars, remembers the orders, and knows which day the wholesale delivery is late. The AI store is a live test of whether any of that texture is a nice-to-have or a load-bearing wall. For anyone who owns a home in Cow Hollow, it is a small piece of infrastructure risk worth watching. The commercial vacancy pattern on the corridor over the next three years is going to depend, in part, on which model wins on which block.
The summer calendar, briefly
The big set piece already happened. The 48th Union Street Festival ran June 6 and 7, bringing neighbors, locals, and visitors alike to the Marina District, with the iconic Union Street Waiters Race, where local restaurant, bar, and hospitality teams run a relay while balancing trays. The race itself ran Sunday, June 7 at noon.
What is left of summer is the quieter version of the corridor: patios still open until dusk, brunch at Rose's without the June crowd, and the stretch of Union between Fillmore and Steiner walkable at a pace that the festival weekend does not allow. If you have out-of-town guests arriving in August, this is the window where you can actually get into Balboa Café at 7:30 without waiting at the bar.
A short cheat sheet by use case
- Working from a laptop for two hours: Cheminé
- A weeknight dinner without a reservation: Dumpling Union or Turtle Tower
- A first drink that is not at Balbs: Roaming Goat
- Something to hand a house guest as a Union Street loop: Motoring Coffee, then a walk east to Angela's, then dinner at Blue Whale
- The one lunch item to put in the rotation: the chicken caesar at Mama's
What this means for the block
The interesting question for a homeowner here is not whether the openings are good. Most of them are. The interesting question is whether the corridor's identity is shifting in a way that shows up in property values over a five-year horizon. Union Street is quietly recommitting to residents rather than tourists, and that is a healthier substrate than the destination-restaurant cycle that has burned through storefronts here for the last decade. A resident-first commercial strip holds its tenants longer, which stabilizes the walkability that most Cow Hollow buyers price into their offers in the first place.
If you own here and are thinking about a move in the next two or three years — or you are watching the neighborhood from a different part of the city and wondering whether it still holds up — the recent opening class is a small piece of evidence that it does. When you are ready to talk through what any of this means for a specific block, a specific building, or a specific timeline, Regina Gaspari is happy to sit down. Let's connect.
