Good Food & Good Beer
Boston Beer Works, on Brookline Ave. & Yawkey Way, across the street from Fenway Park. Despite its location, it is relatively free of frat types; just a laid-back atmosphere with their own micro-brewed beer on tap and pretty good food. Try the Thai Calimari salad.
Doyle's, in Jamaica Plain, is a typical Irish bar with great food; they have a pretty big menu of pizza, burgers, and the like, and lots of beer on tap; try the sweet potato fries. This is the sort of bar that you'll see families eating at.
Linwood Bar & Grill is a bit more upscale, but they have great BBQ (the best I've had in Boston so far; granted, that's not saying much...), friendly staff, and a really nice dining area. I think that there's music occasionally in the "bar" area (separate from the "grill" area), but I'm not sure.
