This is my local pub. I love this place! Huge rotating beer menu (30ish beers on tap), great food every time I've gone, and awesome specials. If you can make it for their Wednesday specials, I would highly recommend them. The brunch is particularly awesome: Jameson-soaked French Toast, Magners-glazed apples, and Bailey's whipped cream. And that is just my favorite brunch item there. They have a bunch more, that are all good. No one I've gone here with has ever complained about the meal.
Word of caution, check if the local teams are playing - Bruins, Pats, Sox- because if they are, the place will be a mad-house. My only complaints would be the fact it's a sports bar (not a sports person) and that service can be a bit slow when they are busy (duh).
Reservations only accepted for large parties, FYI, but they will tell you how long your wait might be if you call them first.
