Dag Jeroen,
It's great to hear that you'll be spending Christmas in Dublin! 🎄
Restaurants that are part of a hotel are more likely to offer a Christmas Eve or Christmas Day menu, even though it is a family day in Ireland.
You can find some options from
the list here. I'd invite you to contact the hotels that interest you directly. Here are also
a few suggestions to spend Christmas in Ireland.
I hope this helps!
Cheers,
Antoine
