The South Shore has got itself a Napper Tandy’s Irish Pub once again.

Some 10 years after the Napper’s in Massapequa closed, the pub and restaurant group has opened a gleaming, two-story high location in downtown Bay Shore.

The other Long Island locations are in Northport and Smithtown.

The newest Napper Tandy’s opened Friday in the old Nutty Irishman building at 60 East Main Street, which once upon a time served as a firehouse in the middle of the downtown.

“It was a great weekend; a lot of people were poking their heads in and trying to figure out where things used to be,” said Brendan Bulfin, a co-owner and manager at Napper Tandy’s Bay Shore. “Some remember it as the old firehouse or its other incarnations.”

Work started in January and the old Nutty received a top-to-bottom renovation.

The main bar has been moved toward to the front of the building, on the western wall, and there are several areas for eating and drinking on the first floor.

Gone is the big hole in the ceiling that allowed second-floor revelers to look down at the Nutty.

The overall style of decor is modern meets old-fashioned, Bulfin said.

“It’s an old building, so too modern would have been inappropriate,” he said.

Bulfin helped opened the new location along with the original owner of the Napper Tandy’s Irish Pubs, Dan Stapleton, and Stapleton’s cousin, Robert Stapleton, as well as Donal Hogan.

Dan, Donal and Brendan are all from the same area of Ireland.

The pub menu is similar those at the other Napper Tandy’s locations, featuring classic American comfort food along with some special creations from the Bay Shore chef. Among those, the Brussels sprouts app, Jameson steak, and pan seared scallops entree have proven popular.

The ownership team in Bay Shore also expects to be busy catering private events and special events on its spacious second floor — where they offer more of a a coastal vibe.

“We went with the aqua bar and added lots of windows in the back for natural light,” Bulfin said. “We’re on the South Shore so we wanted it to have that Main Street, but also a by -the-water feel.”

There’s also an elevator for easier access to the second floor.

“We wanted to make it comfortable for all guests to go upstairs,” he said.

“There’s a lot of great things happening in Bay Shore and we definitely want to be a part of it,” added Bulfin, who bartended and managed at the Smithton location for years. “Since Day 1 everyone in the area has been more than helpful, which is another cool thing, that sense of community.”
