John Harvard’s Brewery & Ale House is bidding Cambridge goodbye.
The storied pub on Dunster Street in Harvard Square will close for good at the end of the month, said Paul Pettas, a spokesman.
“May 30 will be the closing date,” he said in an e-mail.
It was unclear why the company is closing its flagship Cambridge location. When asked, Pettas declined to comment.
The remaining four locations that operate under the John Harvard brand — in Framingham; the Union Station Brewery in Providence; at Holiday Valley in Ellicottville, N.Y.; and at Jiminy Peak in Hancock — will remain open for business, he said.
The Cambridge location opened at 33 Dunster St. in 1992. The news of its looming demise was reported by Boston Magazine on Tuesday.
“After nearly 30 years in Harvard Square, John Harvard’s Brew House has decided to close its doors permanently,” a company statement said.
“It has been a honor and pleasure being part of the Harvard Square community and we are grateful to everyone in the community for supporting us . . . ”
John Harvard’s was known for hosting live entertainment and serving up basic tavern fare, with menu items like the Dunster Burger (a half-pound black angus beef patty topped with whiskey barbecue sauce, smoked gouda, and bacon), Harvard Squares (beef sliders with American cheese and caramelized onions), and an assortment of sandwiches, salads, and fries.
At one point, John Harvard’s operated several out-of-state restaurants, including in Pennsylvania, Connecticut, Washington, D.C., and Delaware.
Centerplate, a hospitality company headquartered in Stamford, Conn., acquired John Harvard’s in 2010.
