Firefighters were battling a blaze Monday afternoon at Billy & Madeline's Red Room Tavern in Hanover.

Flames were visible through the windows and attic, and heavy smoke poured from the three-story building at the corner of Mount Pleasant Avenue and Parsippany Road. Firefighters were using ladder trucks to douse flames from above.

Authorities at the scene said the owners of the tavern live above the bar and restaurant. Though there was no immediate information about injuries, authorities said everyone had been evacuated from the building. Several were also taken to the hospital for treatment of smoke inhalation.

The smoky fire was causing traffic delays on Route 10 in the Whippany section of Hanover Township. The restaurant's parking lot has an entrance from that highway.

The bar and restaurant has been a local stop for decades, according the tavern's website: "It opened in 1933 by Billys parents as Fornaros Tavern. It became Billys Red Room when Billy officially took over in 1959. The legendary Billy & Madelines Red Room Tavern was created in 1980 when Billy married the love of his life, Madeline."
