The 66-year-old actor, best known for his roles in movies such as Reservoir Dogs, Armageddon and The Big Lebowski, was spotted eating out at Bubba’s Fish Market in the south Dublin town on Saturday evening.
The star is in Dublin for the filming of the new season of the Netflix hit, Wednesday, directed by Tim Burton and co-starring Jenna Ortega.
One fellow diner told the Irish Independent that nobody in the restaurant had recognised the famous actor in their midst.
“No one at my table recognised him except for me; I’m a huge movie buff, so I knew him straight away,” Oisín Heavey said.

“We were having dinner, and he was at the table beside us for 90 minutes.”
After the star finished his meal and left, Mr Heavey said his wife noticed a crowd gathering outside.
“We could see there were loads of people outside, kind of looking up towards where he had gone, so we assumed he was spotted,” Mr Heavey said.
“When we went outside, there was actually a very vicious fight going on, and that’s what everybody was looking at.”
The fight had started on the street outside The Dalkey Duck pub, and they noticed Buscemi watching the altercation.
“Steve Buscemi was kind of standing there completely unnoticed,” Mr Heavey said.

“He was very close to it, but he held himself back from breaking it up. He stood over the guy on the ground for a few seconds, and the fight naturally broke up after that.
“Some people said he broke up the fight, but he didn’t. He tried to help, which is more than most people would do.”
The actor then left and went around the corner from where the fight had happened.

“He was very nice, friendly, and engaging. He looked me in the eyes and talked to me properly,” Mr Heavey said.
“I just wanted to say to him that it’s not a representation of Ireland and I hope he enjoys his trip.”
