While travelling round Ireland (not with a fridge, mind you) last year, I found "McCarthy's Bar" in a bookstore and immediately decided to buy it.
I found Pete McCarthy's book makes for an excellent read, highly amusing, never boring, and very accurately describing parts of Ireland where I had just been in a way that let me say: "yep, he's been there allright".
It's not all about Dublin, it doesn't really do as a travel guide but it portrays this country in a way that I have seen, too.
If you liked "Round Ireland with a Fridge" and enjoy the humourous travel writing of Bill Bryson, you will most certainly enjoy "McCarthy's Bar"!
