The Sunset House pub, which was the scene of a gangland murder two months ago, will re-open this week.
Paul Gannon, the brother of Social Democrats councillor Gary, have taken over the lease of the inner city bar and will open it under the name The Brendan Behan on Thursday.
Dissident republican Michael Barr was shot dead in the bar in April. It is believed the murder may have been linked to his association with the Hutch mob.
If confirmed, he would be one of eight people murdered in the ongoing Kinahan-Hutch feud which has terrified the capital.
Eamonn Cumberton (29) has been charged in connection with Barr's murder.
Mr Gannon (22) said he is keen to revitalise the pub and stressed that any links it had with organised crime have been severed.
His family already own Ned Scanlon's early house on the southside which he runs with his brother, Brian.
"We know what the pub is about, we've seen it all our lives and what happened recently was terrible, but we know what the pub can do for the community," he said.
"Our family have a good name and we want to get back in and show that the inner city is a good place.
"We want it to be a place where people can come and have a cup of tea as well as a pint."
Mr Gannon said he wants to move the pub's image away from its previous association with gangland crime.
"My family is not involved in organised crime and never will be. We're leasing the building straight from the owner," he said.
"We're changing the name, doing the whole place up, it's a fresh start."
Local reaction has been overwhelmingly positive, he said, and several people in the area have been in touch to wish him luck with the new venture.
"We have a good name and people know what we have done over in Ned's, so everyone is just delighted," said Mr Gannon.
The pub was a local hub with regular entertainment including bingo.
"We'll hopefully bring it back to what it was six or seven years ago," said Mr Gannon. "It'll take a few weeks to pick up, but once people come in and see the place it should pick up."
The name was chosen by the new boss's father to commemorate writer Behan.
Gary Gannon said he was not surprised when his brother announced he wanted to take over the former Sunset House.
"We grew up here and it's no surprise that he wants to put roots down here," he said. "As long as he sticks to his studies we're all right behind him."
