BEVERLY — The husband-and-wife team that once ran a tony restaurant in Beverly Farms is turning its attention to hamburgers.

David and Sherri Bergmann plan to open a new restaurant called BurgerWorks next month in the North Beverly Plaza. The couple, however, are not completely abandoning their upscale roots.

"It's a burger place, but it's more of a high-end burger place," David Bergmann said. "Not expensive, but just very high quality."

The Bergmanns, who live in Prides Crossing, ran Yanks restaurant on Hale Street for four years before selling the business in 2003. Yanks was named to Boston Magazine's "Best of Boston" list twice and received a favorable review in The New York Times.

Bergmann said he and his wife enjoyed running Yanks, but also realized it would be difficult to expand beyond a single restaurant, as they hope to do with BurgerWorks.

"With a high-end restaurant like Yanks, you're really dependent on your chef for the quality of it," he said. "We couldn't expand and have Yanks 2 or 3 or 4. We wanted to get into something that was a little bit more family-friendly and would allow us to expand into multiple units. Unfortunately, you can't clone great chefs, but once you get a recipe for really great hamburgers, then you can take that various places."

The price of a hamburger will start at $6.25 at BurgerWorks, Bergmann said. It will also sell french fries, onion rings, shakes and smoothies, as well as "sliders," a group of three mini-burgers.

Bergmann said BurgerWorks will be a "green restaurant," with no china or silverware. The plates and forks will be made out of bamboo and sugar cane that will be composted at Brick Ends Farm in Hamilton, he said, while the Angus beef will come from grass-fed and humanely raised cattle.

"We really want to make it as green as possible," Bergmann said.

BurgerWorks will be in the North Beverly Plaza on Route 1A between Radio Shack and Dress Barn, at the site of another burger place, Big Bully's, which closed last year.
