The prominent Stockyard Food and Spirits steakhouse restaurant in Brighton has closed indefinitely.
A sign on the building and postings on the eatery's website and social media pages say the restaurant is closed until further notice due to "renovations."
The establishment's owners have not returned messages over the past week.
The restaurant on Market Street, visible from the Massachusetts Turnpike, opened 42 years ago.
The late Corneilus "Neil" Manning and his wife, Lillian, bought the property and built the restaurant. His sons, Mark Manning and Neil Manning Jr., now run the business.
The Mannings have not returned messages left for them this week, nor has the restaurant's general manager, David Casey.
The head chef of the steakhouse was reached by phone but referred comment about the restaurant's status to upper management.
The restaurant property, which includes a lot with more than 125 parking spaces, comprises just more than one acre of land valued at a combined $2.35 million, according to the city's assessing department website.
Speculation has spread that restaurateur Michael G. Conlon Jr. is in line to purchase the Stockyard. Reached last week, he declined to comment on the record.
On March 9, 2012, Conlon filed paperwork creating two separate limited liability companies named Original Stockyard and Vineland Street Realty. The Stockyard restaurant's property in Brighton is located at the corner of Vineland and Market streets.
Conlon and his brother-in-law and business partner Joseph Greene run several restaurants in Boston: the Blarney Stone in Dorchester, West on Centre in West Roxbury, the 21st Amendment in Beacon Hill and the original Paramount in Beacon Hill along with a newly-opened Paramount in South Boston.
The newest Paramount opened in Dec. 2011. Six months before it opened and three months before the current tenants signed a lease agreement, Conlon and Greene filed paperwork with the state creating a new corporation, called "Pmount South Boston, Inc." and, days later, changed the company's name to the then-unannounced restaurant's address, 667 East Broadway, Inc., records from the Secretary of the Commonwealth office show.
Greene, who has not been able to be reached for comment, is not listed on paperwork for the two companies created in March.
