A small legit Irish bar, with wood paneling throughout the interior makes for an intimate neighborhood feel. Monterey pub is a great place to spend a late weekend afternoon or wolf down comfort food with friends. A perfect place to stop by after a visit to the museums in the North End, as well. The pints are well-poured and the drinks are good and cheap. The food is super-hearty. All of the beef seems to be marinated in Guinness (which is excellent). Try the boxty's if you're feeling adventurous.
This may be obvious, but if you're looking for the pub, it's on Monterey street (look for the YMCA at the end).
