A popular Adams Corner eatery, hair salon and coffee shop are among the businesses that are closed this week after a fire struck the building they occupy at 756-762 Adams Street last weekend.

The Boston Fire Department responded to the scene at 2:34 a.m. on Saturday. The two-alarm fire was confined to the basement area, but it caused extensive smoke damage to the first-floor shops, the department says, estimating damage at $700,000. Fire investigators are still trying to determine the cause. There were no injuries.

Ken Blasi, who owns the building with his brother, believes that the cause of the fire may have been electrical. His business, the popular Fat Belly Deli and Blasi’s Café, is among the businesses that will remain closed while the damage is evaluated. Other impacted businesses include Folan Family Dental, PS Gourmet Coffee, Village Touch, Bruins Daily and Carpenters Local 67. (The Carpenters Union has relocated their offices to its regional headquarters at 750 Dorchester Ave. for now.

“When I got here I was overwhelmed,” Blasi told the Reporter. “There as a ton of smoke.”

The Blasi family has owned the building since 1959. His father worked for and then bought the Adams Hardware Store, which operated in the village for decades. Ken and his brother converted the former store into a bar and restaurant in the 1990s.
