Lennon smiled for the camera as he and his family posed with their pints of Heineken during a staycation in the capital.
According to Dublin Live, The River Bar hosted the former Celtic manager and his family on Sunday evening.
The boozer shared photos of Neil and his guests to their Facebook page, saying: “Look who dropped in for a pint.”
Lennon’s 13 year career as a football manager ended earlier this year when he resigned as Celtic manager.
He called time on his second spell in charge of the Hoops in February after facing serious backlash from fans.
Lennon, who also played for Martin O’Neill’s star-studded side, picked up five Scottish Premier League titles along with four Scottish Cups and two Scottish League Cups.
He also featured in the epic UEFA Cup defeat to Joe Mourinho’s Porto in Seville in 2003.
The 50-year-old first took the reins at his boyhood side in 2010 and guided the side to three Premier League titles before resigning in 2014.
