This excellent restaurant opened in Dublin about 25 years ago and I have been a regular visitor since then but my visits became less frequent with the passing of time.
Up until recently I thought that this was a Dublin based business but I recently discovered a few days ago that The New York Elephant & Castle [the parent company] opened in 1973.
The restaurant in Dublin is highly recommended but in my opinion it is not nearly as good as it was twenty years ago. However, it is still one of the best option in Temple Bar especially if you like American Style dining. Be aware that it can be difficult to get a table at any time of the day.
