About Dennys

Dennys combines people with their signature eggs, burgers, frying pans and everyday values for more than 65 years. Enjoy dinner 24 hours a day. Driven by their brand purpose, Dennys is a 53-foot mobile kitchen that allows them to do what they do best, providing food to those in need after natural disasters and emergencies. Every time they deploy, their mobile relief dinner travels to the local community, suffering from fires, tornadoes, hurricanes, earthquakes and other disasters, providing local residents, emergency workers and others with free fresh pancake breakfast, including bacon, coffee and drinks. Provide a little comfort when they really need it. You can keep track of the current location of the Mobile Relief Diner on Twitter.
