"I know they've all been here," Hoole said. "Clinton has been here, Gore has been here ... ."
The restaurant is often visited by local and state dignitaries as well, including former Gov. John Lynch.
The most recent high-profile candidate to visit was U.S. Senate candidate Scott Brown. The former Massachusetts senator stopped by twice in the last month to greet customers.
More candidates are expected as the campaign season progresses.
Brown's visits left an impression on waitress Julie Duddy, who has worked at MaryAnn's for two years.
"He was my first bigwig," she said.
Nicole Coffey, an employee for eight years, recalled meeting Clinton and getting a chance to shake the former president's hand in 2009.
"The place was a zoo," she said. "I remember he had such soft hands."
Well-known athletes stop by, too, including former Boston Red Sox players Jason Varitek and Bill Mueller.
But the most popular athletes in Derry yesterday were members of the Pinkerton Academy girls lacrosse team. They celebrated their state championship victory by having breakfast at MaryAnn's, Lewis said.
Lewis, who has worked at MaryAnn's for 20 years, said the chance to meet loyal, friendly customers each day makes her job so enjoyable.
Next week, Lewis said, she's looking forward to seeing the same group of approximately 20 motorcyclists who have stopped by MaryAnn's each June for years on their way to celebrate Motorcycle Week in Laconia.
"It's such a diverse group," she said.
First-timers or regulars, famous or not, it all comes down to the food.
Just ask Derry resident Richard Cowette, 76.
"I've never gotten a bad meal here," he said, polishing off breakfast yesterday.
