Oakland Denny's Shut Down Due to High Crime, Following In-N-Out Closure

Another American staple in the food biz is fleeing Oakland because of increased crime ... the only Denny's in the city closed for good earlier this week, continuing a troubling trend.

While Denny's officials reportedly wouldn't speak on camera, a notice taped to the door cited the "safety and well-being" of employees and guests as the chief cause of the closure -- which sounds a lot like increased crime's become an issue for the 24-hour restaurant.

Employees were reportedly notified of the closure just a day before the 54-year-old Denny's officially shut down ... and the company promised to find the employees positions at other locations if they could relocate.

It'll be a minor commute for Oaklanders to get a Grand Slam at the Emeryville location, a 3-mile difference ... but it's just the latest in a shocking trend of closures precipitated by rising crime in the Bay Area.

This Denny's location had reportedly fallen victim to break-ins-robberies and violent crime ... just like the In-N-Out that's also hightailing it out of town.

As we reported ... In-N-Out's COO Denny Warnick cited crime as the major reason the super popular food chain was heading out of business -- though they'll stay open until late March.
