Stay away long enough and you might think that Irish pubs are all the same. But go more than once a year, and you’ll remember that the delight lives in the details, whether the taste of a perfectly poured pint, or the quip of another patron. The fun need not end on March 17. No, heed the words of Liam Maguire, who runs the Falmouth pub that bears his name. He tells of the call he got from a woman one St. Patrick's Day. "I want to reserve a table because we came last year and we had such a great time," the woman told Maguire. ‘‘If you had such a good time,’’ Maguire said, ‘‘why didn’t you come back before now?’’ In the spirit of St. Patrick’s Day, we offer a tour of 10 favorites in the region.
