Ross' Restaurant will make way for a new Interstate 74 bridge by relocating in Bettendorf.
On Friday, the familiar sign remains a real Bettendorf landmark.
"I just feel like I'm at home," said owner Cynthia Ross-Freidhof.
And Ross' Magic Mountain is the stuff of legends. It's been the meal of many a late night partier over the years.
"It's a first experience for some people, I'm sure," said customer Linda Rinnert, Muscatine.
This culinary concoction fired the sparks between Linda and Gerald Rinnert more than 40 years ago.
"I can get funny on Pepsi," she chuckled.
Nearly four years ago, President Obama stopped by.
"President Obama, I can't believe this is real," Cynthia recalled saying at the time. "And he said, 'Cynthia, I told you I was coming,'"
He issued a gastronomic challenge by offering to buy Magic Mountains.
"Anybody in the press corps has to eat the whole thing," President Obama said.
It's all part of the folklore dating back more than 75 years and spanning three generations.
"It's so significant being a part of people's childhood memories," said General Manager Melissa Freidhof-Rodgers.
Now, the mom-and-pop diner is on the move.
"Frank's was just the right fit at the right time," she said.
Ross' will be able to move all of this mystique and play off its nostalgia while also adding a lot of new features.
In addition to the menu favorites, they'll add vegetarian and gluten-free selections. There will also be more coffee drinks and a full bar.
It will be the end of one era and the start of another for customers and longtime staffers.
"Everybody gets to know each other," said server Stephanie Hughes. "It's like our own little world."
Still, change can be tough.
"It's going to be really hard to leave here," Cynthia said.
After all, she began working there at age 12.
"The history is following us," she said. "The soul of the people that come and the soul of the owners."
They'll be keeping Bettendorf's "magic" in the Magic Mountain.
"We'll be just fine," she concluded. "I really believe this."
