Spoiler alert: they hate most American things unless it goes well "with a pint", "after'a night'o drinkin'" or "with a cuppa tea".

Bewilderingly enough, they all liked Fritos.

Occasionally the US gets punked when they do videos like "Irish People Try American Cupcake Flavors" and they give them a cupcake frosted with Easy Cheez and topped with bacon and cornflakes and Circus Peanuts that is obviously an outrageous Millenial joke stunt creation and not something a typical person would eat.
