The U2 frontman and his wife Ali closed down Finnegan's of Dalkey in his native Dublin for the private event as Obama and her two daughters, Sasha and Malia, arrived for the meal, but they weren't alone - around 60 other guests were also in attendance for the luncheon.
Dishes on the menu included fish and chips, cottage pie and smoked bacon, and the owners of the family-run pub even made an extra effort to make the Obamas feel at home by hanging an American flag above the main entrance.
Addressing the high-profile lunch meeting, Bono says, "We talked about everything and nothing. It was a family lunch."
U.S. President Barack Obama was not in attendance at the meal as he was meeting with world leaders at the G8 Summit in neighbouring Northern Ireland.
