Done a few trips to Dublin & watched the Darts Grand Prix there a couple of times, this place was the cheapest of all the lot for drinks, a good old fashioned boozer with a few characters, always a warm welcome though.
free irish stew on offer every lunchtime as well. definately worth it for a few cheap ones
