Union Street's New Arrivals Keep Different Hours Than the Ones Leaving

"The economy changed, our clientele has shifted, and so everything just kind of created this little perfect storm of the universe being like, 'OK, maybe now is a good time to say goodbye,'" Angie Denardo told SFGATE in late September.

Denardo manages Corsagna Deli at 1668 Union St. The deli served its last sandwiches yesterday, October 2, with a champagne toast for customers, after 46 years. Three weeks earlier and two blocks west, a restaurant group reopened a space it had left two years ago, this time as an evening-only hand-roll and cocktail bar. Put the closings and openings side by side and a pattern appears in their hours. The businesses arriving on Union Street are each built around one part of the day and one kind of customer. The business that just closed was built around weekday daytime hours, and that schedule kept it open for almost half a century.

A Deli Built Around Raising Kids

Corsagna's history is the history of that schedule. In the 1970s, Egidio Giampaoli took over an accordion studio at 1668 Union and turned it into an Italian bakery. In 1980 his daughter Elvira Giampaoli took it over and made it a deli because customers kept asking for sandwiches. She had left a corporate job at Bank of America for it. "She wanted a job that gave her the flexibility to be more of a mom," Denardo said.

That reason held for a second generation. Denardo and her sister, Paola Berdichevsky, were both "raised behind the counter," and both stayed on as managers. SFGATE reported that the job still appealed to them for the same reason it appealed to their mother: "As a business only operating on weekdays during the day, it gave them the flexibility to raise their young children."

The menu fit those hours too. The pesto chicken panini and the Mr. Italiano, made with salami, coppa, mortadella and provolone, were the best sellers. Denardo said the reasons for closing went beyond what it costs to run a business in San Francisco, though cost played a role. Her explanation starts with a changed economy and ends with a shift in who was coming through the door.

Kaiyō Left for One Reason and Came Back for Another

The return of Kaiyō shows the same change from the other side of the clock.

Restaurateur John Park opened the original Kaiyo, a Japanese-Peruvian Nikkei restaurant, on Union Street in 2018. He later opened two more Kaiyo locations at the Hyatt Place San Francisco, then closed the Cow Hollow restaurant two years ago. Eater SF reported his reasoning: the team felt the city "wasn't busy enough to accommodate two similar restaurants" while San Francisco was still recovering from the pandemic.

Eater's explanation for the return is just as direct: "As office workers returned," Park's Brick by Brick Hospitality Group turned back to Union Street. Kaiyō Handroll Bar opened at 1838 Union St. on Friday, September 11. Its posted hours start late:

• Tuesday through Thursday: 4 p.m. to midnight, kitchen closes at 10 p.m.
• Friday and Saturday: 4 p.m. to 1 a.m., kitchen closes at 11 p.m.
• Sunday: 4 p.m. to 9 p.m.

Monday isn't on the posted schedule.

The kitchen team will be familiar to longtime Kaiyo diners. Chef Alex Reccio and chef de cuisine Kenji Sawada run the kitchen, and Danny Louie runs the drinks. The menu centers on hand rolls made with cilantro rice or chicha morada rice, which is infused with Peruvian purple corn instead of standard sushi rice. One is a lomo saltado roll with A5 wagyu and shoestring potatoes. Another is an arroz con pato roll with flash-seared roast duck and sansho pepper. Around the rolls are aji gallina croquettes and a scallop udon with mentaiko sauce. The bar serves a shiso-and-sakura margarita called Deiji, alcoholic and non-alcoholic soft serve, and zero-proof drinks such as Kukki, made with matcha, pineapple juice and Oreo milk.

The plan for after the kitchen closes makes the most direct case for the late hours. Park wants the room to run as a cocktail lounge with limited food, DJs and a later closing time. "It'll be more of a sophisticated cocktail lounge than anything else," he told Eater. The two closings were six blocks apart, but the business case is the same: weekday daytime trade was thinner than it used to be, and evening trade was strong enough to justify reopening.

Dantone Milano's Deadline Came From Someone Else

Not every departure fits that explanation, and the street's third big change this fall happened for a different reason.

Dantone Milano, the shoe boutique at 1784 Union St., has been run by Farzad Arjmand since 1985, according to the shop's own website. On September 30, the San Francisco Business Times reported that the store would close after four decades because the building's new owner had given it 60 days to vacate. The Business Times listing quotes a question in its headline: "Why is this happening?"

Several important details aren't public yet. The available reporting doesn't name the buyer, give the store's last day, describe a closing sale or say what will go into the space. A 60-day notice reported at the end of September points to a departure around the end of November. Until the store confirms a date, anyone who has bought shoes there for years should go sooner rather than later.

This closing doesn't depend on customer traffic at all. It depends on a building changing hands, and that's a separate pressure on Union Street, where many storefronts are in older buildings. A long-running tenant's lease can end when a building sells, however steady its business has been.

The Next Tenants Are Targeting Specific Customers and Hours

The three businesses still on the way follow the Kaiyō approach more closely than the Corsagna one. Each is built around a specific customer at a specific time of day.

Little Maison, at 2240 Union St., will be a play cafe for parents and young children, with a cafe in front and a play space in back. Founder Perichon told the SF Standard who she's designing for: "My target demographic isn't the 3-year-old. It's the 35-year-old with the 3-year-old." The space also says a lot about Union Street's empty storefronts. It's part of a 7,000-square-foot former Sur La Table that had been vacant since 2020. The landlords split it into two smaller spaces that are easier to lease, and Little Maison took the smaller one. Construction started in July and the opening is expected this winter. Designer Cathie Hong, who also designed Sōhn in Dogpatch, is working on a custom play structure, a crawlers' area and a pretend-play zone. The other half of the old Sur La Table is still available. "I'm hoping for an amazing neighbor," Perichon said.

The space will be colorful without being overstimulating, with a custom play structure, a designated area for crawlers, and a "pretend play zone."

Breakfast Little is planned for 2223 Union St., the former Gamine space. In April, the San Francisco Chronicle reported that owner Andrew Martinez-Perez had confirmed the location but didn't have an opening date. Hoodline reported the same that day, and no later update has appeared. As a morning concept, it would put a new business in the daytime hours Corsagna just left. Its opening date is the next one to watch on the street.

The Yard Strength Training announced in June that it would open a 4,300-square-foot gym at 1906 Union St. in September 2026. No report has confirmed that it opened, so call before you go.

None of these three is set up the way Corsagna was, as a small counter serving the same lunch crowd five days a week. Each is opening for a defined group at a defined hour: parents of young children during the day, breakfast customers in the morning, a gym's members on their schedule, and evening diners at Kaiyō.

What's on the Street This Month

The fall calendar is short. The Union Street Association's public events page lists the June 6–7 Union Street Festival, which has already happened, and doesn't yet show a fall or holiday event for 2026. Here's what's confirmed for the next few weeks:

1. Kaiyō Handroll Bar, any evening except Monday. Doors open at 4 p.m., so an early dinner there misses the late-night lounge crowd entirely.
2. Dantone Milano, before the end of its notice period. The store hasn't announced a last day, but the 60-day notice was reported September 30.
3. Saturday, October 31, 2 p.m. to 10 p.m. CrawlSF's Halloween pub crawl includes Cow Hollow, with Union Street Ale House at 1980 Union St. as a check-in point. Expect bigger evening crowds on that stretch of the street that day.

If you take the bus, SFMTA's route page currently shows the 41 Union as suspended with no current service. The 45 Union/Stockton runs daily from 5 a.m. to 10 p.m. That covers Kaiyō's dinner hours, but not a 1 a.m. closing.

Dantone Milano's 60-day notice after its building sold is a reminder that on Union Street, a tenant can lose its lease simply because the building changed hands. If you own property in Cow Hollow, or are weighing a building with retail on the ground floor, it helps to know how a sale affects existing leases before you make any decisions. James Kil works through those questions with owners and buyers at the underwriting level, from existing leases to how a lender will treat the building.
