It isn’t really a St. Patrick’s Day celebration without a pint of Ireland’s greatest export after bog butter and poets. Unfortunately, as anyone who has spent St. Patrick’s Day in New York City knows, a fresh pint of lovely Guinness can cost you a king’s ransom (i.e., several dollars more than that barbaric swill known as American lager). Fortunately, Expedia did some research and found the cheapest and most expensive places for buying a pint of Guinness on St. Patrick’s Day. The results are more than a little surprising.
