Fagan's Pub / restaurant which was recommended by the concierge of the Croke Park Hotel concierge (about 15min walk). If the restaurant is good enough for Bill Clinton and Bertie Ahern, it is a good testament of service and quality of food.
Excellent good choice of food and value for money, friendly and welcoming.
On the first nigh we did not book - big mistake, had to wait for an available table. The place was packed, bar staff very busy.
