Multiple options for restaurants have now been found for the towns of Lahinch, Doonbeg and Killarney. For Dublin there are more than 1700 restaurants. Only one is identified here, an Indian cuisine restaurant, just in case we want to have a night out for Indian food like we did in 2011 in Carnoustie.
The dominant cuisine for the restaurants identified from TripAdvisor is seafood. Lots of seafood! There are other choices, but it is clearly seafood that Ireland is known for.
