If you are into craft beer, go to Trillium. It is expensive, but it’s some of the finest New England style IPA in the country. Other styles are good there too, but you have to at least try their IPAs (there are countless minor variations that are all very similar, you can’t go wrong).

If you get access to a car (make a friend!) take a drive to Treehouse for beer too. For a long time there was just one location and it was the only place to buy it. Now there are a handful of locations but all are outside of Boston.
