I'm not aware of anywhere specialising in Halal food, it's a fairly minority requirement in Ireland.

Unless there are restrictions around Halal not being prepared in the same kitchen as non-halal though, I can't see why most venues couldn't cater for that request.

You could try the Citywest hotel, I was at a wedding afters there and I'm about 99% sure the food would have been halal (bride is my friend and she eats halal food). I don't know much about the specifics of the food prep etc so I hope I'm not wrong. They had a civil ceremony there too
