Rascal Flatts' Unstoppable Breakfast is a biscuit topped with country-fried steak, eggs, American cheese, country gravy and three strips of bacon, served with a side of hash browns.
The new Rockstar menu, with items starting at $3.99, will be available in Denny's on Tuesday.
The Denny's Allnighter program also features an Adopt-A-Band initiative, which provides up-and-coming bands with free meals, and lets fans meet the band at predetermined Denny's
locations post-concert. --Karl Greenberg
