White Castle is staying open later.

The Ohio-based burger chain has announced that 91% of its locations are open until 1 a.m. or later and 72% are open for 24 hours seven days a week, according to QSR.

In a press release about the late-night hours, the fast food chain dubbed itself “Night Castle.”

“White Castle has always been there for our Cravers when it matters most — even when the clock strikes midnight and beyond,” said Jamie Richardson, the vice president at White Castle, in a press release. “Night Castle isn’t just a moment in time — it’s a state of mind. Whether it’s summer nights, weekend outings or just a craving that won’t quit, we’re proud to be the place people turn to for craveable flavor, great value and unforgettable memories.”

In May, McDonald’s announced it would extend its hours.

According to People Magazine, the fast-food chain plans to keep select locations open until midnight or later. The change will impact the “vast majority” of U.S. locations, a spokesperson told The Independent.

Restaurants in non-traditional locations like airports and shopping malls will likely not extend hours, the company said. Franchise owners will decide which menu items will be available during the late-night hours.
