The 64-year-old presenter and Katie Alexander, 42, looked happy together at the American-style venue.
With Eamonn chomping on £9 “Full Fry” breakfasts and £6.50 soup of the day.
Staff said the telly star appeared “quite frail” amid his health issues with his back and came in using a wheeled frame.
He was also seen being helped into a car at Belfast City Airport on arrival on August 16.
It comes after his wife Ruth Langsford, 64, announced they are to divorce.
She found messages from another woman on a laptop at their home.
Last week, Katie’s ex-husband George Alexander told The Sun on Sunday he felt sympathy for Loose Women presenter Ruth over their split.
One staff member at “budget friendly” Papa Browns, in Carrickfergus, said of Eamonn’s visit: “He came in four days in a row. I noticed his girlfriend had an English accent. They looked happy.
“He appeared quite frail and it took a minute to recognise him, but he was always very polite and friendly.
“Both of them appeared at ease with being seen together. Eamonn really enjoyed it.”
Eamonn has had to deny reports he has been taken off air in a staff shake-up at GB News.
He posted on X he was on a “summer holiday”.
Relationship counsellor Katie was dropped off at Belfast City Airport yesterday afternoon before flying back to England without Eamonn.
During the trip, he is understood to have visited family in Holywood, a coastal town 20 minutes from Belfast city centre.
A local barman said he saw the presenter in the high street.
Katie, a divorced mum from Yorkshire, was given an insight into places close to Eamonn’s heart.
It comes after Ruth was seen on telly still wearing her wedding ring, two months after the couple split.
The Loose Women star was spotted with the diamond band as she modelled her clothing range for QVC on Friday.
