Denny’s is America’s always-open diner: booths, a counter, bottomless coffee and breakfast at any hour. Hungary has none, and all of Europe has one. Michigan has 10, and 7 of them never close. Here they all are with a map and live hours, the closed ones too, and the chain’s story, from a California donut shop to the birth of Nvidia.
The Taylor Denny’s is at 20565 Eureka Road, about 6 miles from DTW and 13 miles from downtown Detroit as the crow flies. It is open 7 a.m. to 10 p.m. on weekdays and nonstop from early Friday until 10 p.m. Sunday, no reservation needed, with breakfast all day, so it works for a Sunday breakfast.39401
The Denny’s in Battle Creek, East Lansing, Jackson, Kentwood, Lansing, Saginaw and Wyoming are open 24 hours, every day. Most sit along I-94, I-96 or US-127, so a late-night drive can end with pancakes.1

In the 1950s Denny’s helped spread Googie, the Space Age coffee-shop style: Los Angeles architects Armet & Davis drew a prototype with a boomerang-shaped roof, followed in 1965 by a zigzag shingled roof. The 1997 Classic Diner went back further, to the fifties stainless-steel dining car.216

“Always Open” on the sign. The “always open” promise on the yellow sign became a slogan in 2011: “America’s Diner is always open.”2620

From a California donut shop to one of America’s best-known diner chains, with the Michigan moments highlighted.
1953
A donut shop in Lakewood
Harold Butler and Richard Jezak opened Danny’s Donuts at Bellflower and Del Amo boulevards in the new suburb of Lakewood, south of Los Angeles. The roughly 900-square-foot coffee-and-doughnut shop never closed.20219
1959
One letter makes it Denny’s
The Los Angeles chain Coffee Dan’s objected to the similar name, so Butler changed one vowel: Danny’s Coffee Shops became Denny’s Coffee Shops. From 1961 it was simply Denny’s.20219
1963
Franchising
Denny’s began franchising in 1963. Most restaurants are now franchised, and the agreements require 24/7 service at most locations, a rule loosened after the pandemic.2
1967
First abroad: Acapulco
The first Denny’s outside the US opened in Acapulco; a year later its stock was listed on the New York Stock Exchange.20
The Grand Slam breakfast debuted in Atlanta, the company says as a nod to Hank Aaron. The original plate is two of everything: pancakes, eggs, bacon and sausage.202124
On Christmas Day 1988, 1,221 Denny’s closed so staff could be home. The AP reported that some had had no locks for decades and others had lost the keys, so new locks went in at about 700 restaurants.222
1993
Nvidia is born in a Denny’s booth
Jensen Huang, Chris Malachowsky and Curtis Priem planned their graphics-chip company in a San Jose Denny’s in late 1992. Huang had started at 15 as a dishwasher at a Denny’s near Portland.6742
In the early 1990s Black customers and six Black Secret Service agents sued the chain. The 1994 settlement paid $46 million to the plaintiffs, usually quoted as $54 million with legal fees; afterwards the company changed its hiring and supplier programs.27228
1997
The Classic Diner
The first Denny’s Classic Diner, a modular building styled like a fifties diner, opened in Fort Myers. The same year the parent company Flagstar went bankrupt and re-emerged as Advantica.25
Denny’s first Super Bowl ad promised a free Grand Slam on February 3 from 6 a.m. to 2 p.m.; about 2 million people were served in eight hours. It happened again in 2010.232425
2013
Getting married at Denny’s
The Fremont Street Denny’s in Las Vegas opened its own wedding chapel; on Valentine’s Day 2026 it held free weddings.49
Two franchisees who already owned six Michigan Denny’s bought the former Ponderosa building in Traverse City; the Denny’s opened that spring with 120 jobs.37
2017
Europe’s only Denny’s
Europe’s first Denny’s opened in Swansea, Wales; on Christmas Day it hosted the city’s homeless people.472
The Holland Denny’s closed abruptly on October 18, 2019; it was one of seven Michigan restaurants run by a bankrupt Lansing franchisee.36
2020
The end of always open
Because of the pandemic many Denny’s closed for the first time, and many now keep shorter hours.250
2023
A plaque at the booth
A plaque went up at the San Jose corner booth where Nvidia was planned. In Michigan the same year, Denn-Ohio, running ten Denny’s in three states, filed for Chapter 11.423435
2024
150 closures
The company announced it would close about 150 of its weakest restaurants; closures continued through 2025 and 2026.31232
2026
Taken private
The $620 million takeover closed on January 16 and Denny’s left the stock market. In February the Kalamazoo (1979) and Grand Rapids (1981) restaurants, Michigan’s two oldest known Denny’s, closed.293033
04 / Diner stories
Doors without locks and a billionaire dishwasher
Why Denny’s is more than a restaurant chain.
🔒
Doors without locks
Until Christmas 1988 many restaurants had never closed, so they had no locks.22
💻
The graveyard shift and a billionaire
From 1978 to 1983 Jensen Huang washed dishes, bussed tables and waited on the graveyard shift at a Denny’s; he says it taught him humility and hospitality.742
☕
What Nvidia’s founders ordered
A Lumberjack Slam, a Moons Over My Hammy and a Super Bird sandwich, with plenty of coffee.4342

🥞
Not our palacsinta
The American pancake is made with baking powder, thick and fluffy, and eaten with maple syrup, blueberries or even crispy bacon; nothing like the thin Hungarian palacsinta.1514
🌙
The late-night meal
The diner was once the country’s most common 24-hour public place: for night-shift workers, people leaving bars, college students.1326
05 / Michigan
Why only ten?
Denny’s is rare in Michigan: ten restaurants statewide, while California had 363 in 2023. Detroit has its own kind of diner, the coney island.382

06 / Europe and Hungary
We don’t have one, which is why it’s worth a try
There is no Denny’s in Hungary or anywhere in Central Europe; the Hungarian Wikipedia has no article on it. Hungarians know the American diner from films.182

John Travolta’s weatherman has his own booth at a Denny’s in the film.10
Why it surprises a European
The diner is quintessentially American: open around the clock, no reservation, breakfast at any hour. Seven Michigan Denny’s still work that way.131
