Hello Amanda,
Thank you for providing us with more information about your plans.
I've found that there are many late night pubs that serve food in Newry: the Rice's Hotel, the Yellow Heifer and the Art Bar Funkel to name a few.
I also suggest that you take a look at this article about
County Armagh and
County Down, with a lot of useful information to enjoy your time there and to visit their main attractions.
Since we have a translation option on the forum pages, you're welcome to reply in Spanish if you prefer to do so!
Looking forward to more suggestions from members living in the area!
Valentina
