There are several Boston Beer Works in the greater Boston area - I've been to Canal St., the Fenway location and the one in Salem, MA. Each location has a different vibe, your mileage may vary widely with this local chain.
The Canal St. location is the biggest I've been to. They have two floors, with the bottom floor boasting a very long bar and seating for a pretty big crowd and the top floor having more of a "lounge" feeling with several pool tables and plenty of places to set your drink while you socialize.
Food leaves quite a bit to be desired. Everything is ok, but there's nothing I have had that jumps to mind thinking about the "best dish". Maybe the pizza, but that's nothing to brag about either. Standard fry-o-lator appetizer selection. Decent burgers. They get an "A" for effort on the menu with some creative names but it's a solid "C" in terms of quality and taste. I can't say for certain, but I wouldn't be surprised if this is a stop on the Sysco truck route.
Overall, the beer selection is good, bordering on great. Everything is a house specialty, so engage your waitstaff or bartender to get an idea of the right beer for you. Some favorites of mine include the Watermelon Ale (seasonal and served with a slice of watermelon) and the stout is usually decent.
The pool tables are great.
The one thing this place does extremely well is "Location, Location, Location". Canal St. is between Fanueil Hall and the Boston Garden (where the Celtics/Bruins play) so they're packed anytime there's a game. I wouldn't go out of my way to go here, but if your expectation is to get a decent meal and a beer, you'll do just fine.
