Anna Weinberg's Ken Fulk-designed Champagne-and-oyster bar at 568 Sacramento Street went dark when its lease ran out July 1, leaving the restaurateur with a single room and a May bankruptcy filing behind her.

Leo's Oyster Bar, the retro-tropical Champagne-and-oyster room at 568 Sacramento Street, has closed in the Financial District. Its lease was up as of July 1, and owner Anna Weinberg chose not to renew — "changes in personal circumstances and priorities did not make it viable to pursue renewal," she told the San Francisco Chronicle. There was no sign on the door and no post from the house: the Leo's Instagram account hasn't been updated in over a year, and the closure surfaced this month through Tablehopper and the Chronicle rather than the restaurant itself.

The room was, for a stretch, one of the most photographed dining spaces in the city. Ken Fulk and his then-associate Jon de la Cruz designed it in 2015 — floral wallpaper, a checkered floor, a vintage-tropicalia palette — and in 2016 Bon Appétit handed it the Best Design award in its Best New Restaurants issue, calling it "a Mad Men set you can drink in." The narrow space had previously held the upscale barbecue spot Wexler's. It is now up for grabs.

Leo's was the last full-service restaurant standing from what was once Big Night Restaurant Group, the seven-room operation Weinberg built with ex-husband James Nicholas — a group that at its height included Marlowe (opened 2010), Park Tavern (2011), and The Cavalier. That empire has come apart in pieces: Park Tavern shut for good last month after a failed reboot, and Weinberg filed for bankruptcy in May following lawsuits over unpaid bills from distributor Bi-Rite and from David Stanton, a former partner a judge ordered her to pay $1.1 million in April.

What's left is Tosca Café, which stayed open through a liquor-license scare earlier this year and remains tangled in the Stanton litigation. Weinberg told Tablehopper she is "focused on Tosca's next chapter." A design-award winner closing not on a bad review but on a lease expiration and a bankruptcy docket is the version of a downtown closure that rarely makes the trend pieces — the room looked flawless to the end; the math behind it did not.
