Applebee's will close as many as 80 restaurants nationwide, as casual dining chains continue to struggle with changing tastes.

The locations slated for closure have not been announced. Applebee's owners Dine Brands Global said closures would "be based on several criteria, including meeting our brand and image standards as well as operational results."

The chain will open as many as 15 restaurants during the same period.

Last year, the company closed 99 restaurants. Applebee's same-restaurant sales declines 5.3 percent last year, according to the latest financial filings.

Dine Brands Global also operates IHOP, which saw a 2 percent drop last year.
