America’s 24-Hour Diner

Denny’s is an American casual dining restaurant chain founded in 1953, originally operating as Danny’s Donuts in Lakewood, California. The brand evolved into a full-service diner concept known for serving breakfast, lunch, and dinner around the clock.

Denny’s built its identity around classic American comfort food, including pancakes, eggs, burgers, and its signature Grand Slam breakfast combination.

Operating primarily in the United States with an international presence, the chain emphasizes 24-hour availability, value-oriented menu pricing, and a broad, family-friendly menu. Its locations typically feature booth seating and a traditional diner-style layout.

Over decades of expansion, Denny’s became closely associated with late-night dining culture and accessible, everyday meals. The company is headquartered in Spartanburg, South Carolina, and operates a mix of company-owned and franchised restaurants across multiple countries.
