Faneuil Hall has a least a dozen bars. Some are pretty good. The Sunset grill in Brighton has at least a hundred beers on tap and hundreds of micros.http://www.allstonsfinest.com/ ....Sunset grill is about a 15-20 cab ride from downtown. Worth the quick trip... There are bars everywhere. Too bad it wasn't this weekend, The Yankees are in town. Lots of energy...
Well it's about 45 minutes west from Boston but you should check out the Horseshoe Pub in Hudson. It's got about 80 beers on tap and 2 in casks. I love this place and it's just 7 minutes away from home.
