Personally not a fan of the branding, think it's lazy and stereotypical and just going for the novelty factor. As a result I can understand why it would be confused with a macro brewery trying to gain foothold, especially when you consider the origins of another "oirish" branded beer, Cute hoor.
That said, I quite like the Lidl offerings, although the Mcargles I found pretty awful, the one time i fell foul of the cheap laugh advertising - same as Cute Hoor actually.
I have not been in Waterford since 2012.
