Just a few weeks into 2020, one of San Francisco’s longstanding restaurants is calling it quits after a 28-year run.

French bistro Fringale will permanently close its doors on Jan. 25, the Chronicle reports. Since 1991, Fringale served savory Basque-French dishes at its Mission Bay location at 570 4th Street, but a changing neighborhood has pushed owner Jean-Marie Legendre to shutter.

According to the Chronicle, business at Fringale dropped by 30 percent when the Municipal Transportation Agency’s Central Subway Project began construction six years ago just outside its doors. The project is expected to create a direct transit link between downtown San Francisco and the T Third Line route on 3rd Street.

A growing shift in demographics became a challenge at Fringale after an influx of tech hubs in the area. Legendre suggested that many techies are dodging full-service restaurants, especially during the lunch rush.

"They don’t go out for lunch anymore, because they all get food from their offices," Legendre told the Chronicle’s Janelle Bitker. "The duck confit takes 15 minutes to cook — these people are always on the clock and they want everything right away."

Fringale’s impending closure comes around the same time of two other San Francisco restaurant closures. On Sunday, Noe Valley’s Savor Open Kitchen closed after 19 years in the neighborhood. Owner Charlie Sirhed attributed the closure to rising expenses and, similar to Fringale, a shift in the neighborhood’s demographics.

The Ferry Building’s Brown Sugar Kitchen is also expected to close on Jan. 19 after a short stint in San Francisco. Reasons behind the sudden closure aren’t clear, but chef-owner Tanya Holland told Eater that she wanted to focus her efforts on her flagship location in Oakland.
