Across the street from Fenway Park, this cavernous space is frantic before and after Red Sox games. Don't plan to be able to hear anything your friends are saying. It has a full food menu and 14 brews on tap, including excellent bitters and ales. Especially good are the cask-conditioned offerings, seasoned in wood until they're as smooth as fine wine. The sweet-potato fries make a terrific snack. The North Station branch, near the TD Banknorth Garden, is smaller but equally loud. Open daily from 11:30am to 1am.
