Three-Michelin-Star Chef Christopher Kostow Opens Loveski Deli in Jackson Square

Christopher Kostow, the three‑Michelin‑star chef behind Meadowood, opened Loveski Deli in San Francisco’s Jackson Square on March 4, 2026, bringing his bagel-and-deli concept to downtown. Most local outlets list the shop at 499 Jackson Street at Montgomery and report hours of 7 a.m. to 7 p.m. daily; the San Francisco Chronicle’s listing on Yahoo gives the address as 400 Jackson Street. Kostow said he wants Loveski to be “a lot more than a bagel shop” and not “your average 'Jew-ish' deli."

The Jackson Square location is the third Loveski after an original 2022 opening at Napa’s Oxbow Public Market and a fall 2023 site at Marin Country Mart in Larkspur. The Bold Italic noted the Napa Oxbow location measured about 800 square feet. Kostow and his wife and business partner Martina also operate Charter Oak and Ciccio; the Chronicle copy reminds readers that Meadowood, where Kostow earned three Michelin stars, was destroyed by wildfire in 2020.

Menu items at the new Jackson Street counter include bagels and pastries on display, a smoked salmon bagel photographed by Lea Suzuki for the Chronicle, and prepared plates such as a roasted salmon bowl, a chicken teriyaki bowl, and a chicken Caesar wrap. Loveski introduced a new breakfast burrito at the Jackson Square shop made with pastrami, a smashed latke, and green onion; The Bold Italic warned the burrito “may sell out” and advised customers to “Get the bagel. Get the breakfast burrito before it runs out. Grab something from the larder.”

Kostow’s production notes and accolades traveled with the opening: Chronicle reporting says Loveski’s bagels are made from a 30‑year‑old sourdough starter, boiled in honey Montreal‑style, described as “chewy and well‑seasoned,” and that Loveski bagels “won the Chronicle's blind bagel taste test last year.” The Chronicle also described an expansive “larder section” at the Jackson Square shop featuring Kostow’s pantry creations, explicitly listing “tamari and miso made out of bagels,” a pickle hot sauce, and an everything bagel chili crisp.

The new shop occupies the former Postscript Cafe space, and several outlets reported that Loveski retained much of Postscript’s staff and the existing coffee partnership. SF Standard reported that Postscript will continue to provide beans to Loveski and to “a small list of retail partners.” SFist observed that the speed of the opening “seems to have been helped by the fact that they took over the former Postscript Cafe, and kept much of the cafe staff intact.”

Jackson Square’s mix of tech startups, venture firms, financial offices, antique dealers, and antiquarian book shops shapes how the new Loveski must operate: SFist quoted neighborhood context and a local observer, Joe Kukura, saying the mix “forces this Loveski location to be adaptable.” The Bold Italic framed the change as replacing a beloved local coffee spot, writing that “Postscript was beloved” and calling the new Loveski setup “an upgrade wearing a very unassuming everything‑seed coat.”

Operational details in press coverage list loveskideli.com and hours of 7 a.m. to 7 p.m. daily. Kostow and Martina said they are open to further expansion “if the right opportunity comes along.” SFist noted one local unknown remains whether the Napa location’s after‑4 p.m. Thai fried chicken will be added downtown, writing, “There's no word on whether the after-4pm Thai fried chicken from the Napa location will be making it down here — maybe that would require a fryer and vent hood?”

The Jackson Square Loveski arrives as a chef-driven counter offering a bagel recipe that won a blind test, a retail larder of chef-made condiments, and the retained coffee relationship from Postscript, positioning the concept to adapt to downtown foot traffic and the neighborhood’s mix of office and retail tenants.
