I was commenting about Irish hotels in general terms.

I agree that our breakfast coffee isn't good. ...

I have found the best breakfast coffee in France and Germany. I haven't travelled enough in Italy to comment on their breakfast coffee.
Austria & Switzerland have been some of the best I've tasted followed by Belgium (1st choice for pizzas too). The further south I've travelled, the worse the coffee seems to get
