There's definitely an Irish connection if you're looking for it. And also plenty of Irish pubs (The Druid being my favorite, and Emmet's being the 'unofficial Irish embassy'), plenty of places to see live Irish folk music, art and theater.

But understand that Boston's strong Irish roots have been matched by many other immigration waves over the years including Italians, Eastern European Jews, Salvadorans, Haitians, Vietnamese, Chinese, etc.

Different neighborhoods attracted different groups and developed unique cultures. North End is our 'Little Italy', Field's Corner is our 'Little Saigon', Brookline is known for it's Jewish community, South Boston primarily for it's Irishness - but also has the Polish Triangle area, Allston is our de-facto Koreatown, East Boston & Chelsea for it's Central & South American community, Chinatown for.. well, obvious. You get the idea.
