Rosa Gonzales was crying as she waited in the long line, waiting to eat her last meal at one of her favorite Phoenix restaurants that planned to close its doors after 90 years in business.

She was grieving Sing High Chop Suey House, the downtown Phoenix fixture where she and her husband stopped by every week for a meal.

“It was our favorite place when we first just got married. We’d been coming here since 1971. It was our weekend thing to do,” Gonzales said. “He has since passed, so it holds a lot of memories.”

Sing High, which served its last meal on Sept. 30, is among several longtime restaurants rooted in decades of history, relying on loyal customers and an appreciation for the past to survive. Others have recently closed doors.

Other restaurants that have closed include Tom’s Tavern in downtown Phoenix (87 years), Riazzi’s Italian Garden in Tempe (72) and Park Central Deli in midtown Phoenix (60), according to A few years ago, Monti’s La Casa Vieja, Tempe’s oldest restaurant, shut down after nearly 60 years.

Such longevity is unusual.

About 70 percent of restaurants that make it past year one will fail within the next three to five years, according to a 2016 analysis by Perry Group International.

Michelle Dodds, a historic preservation officer for Phoenix, said owning and operating a restaurant for a long  time is no easy task, and Phoenix residents value the historic touch restaurants bring to the community.

“There’s a real appreciation, more so now than ever, for a property that offers something unique, something that has a history, something that’s just not some cookie-cutter thing you can see anywhere in the U.S.,” Dodds said.

Some restaurants, even if they’re in historic buildings, aren’t eligible for historic designation, she said, because they’ve had to alter some parts to accommodate the business.

Dodd said her office focuses primarily on buildings of historical significance but also reviews demolition requests for commercial properties that are 50 years  or older. They can consider the building for inclusion on the Phoenix Historic Property Register, which could protect it from future demolitions.

“Instead of someone coming in one morning and getting a permit for a demolition and going out that afternoon and demolishing what could be an important building, we have a 30-day hold for us to look at that property,” she said. “Maybe we’ll discover that it’s eligible for the register.”

To be considered for the register, a building must be 50 years or older and significant due to its architecture, design, an important person visiting, or an event that took place there. It must also have good integrity, meaning it has not been altered significantly.

Dodds said many Phoenix restaurants have honored history by opening shop in buildings of historic significance.

MacAlpines’s Diner & Soda Fountain is in a building that housed a pharmacy in 1929. The diner, with a jukebox along a wall, is stocked with an array of soda flavors, old- fashioned milkshakes and homestyle cooking inspired by an earlier era.

Monica Heizenrader, the owner, said she wanted to preserve the building’s history.

“We decided we wanted to buy MacAlpine’s because we didn’t want to see it close,” she said. “The previous owner was going to auction everything on eBay, and we just felt it was such a piece of American and Arizona history, it was really special.”

Other restaurants, like homegrown Carolina’s Mexican Food, which has been churning out meals since 1968, and the Stockyards, built in 1947 as a gathering place for cattlemen, still offer customers a taste of history.
