This place is the first place I've given 5 stars to. I don't give these out lightly. The Mason is a great mix of atmosphere and nicely curated list of craft beers. The place is dark and has hand-picked furniture and art, and hosts a couple of live events each week.
There's a nice little patio in the back, as well. It is the perfect (as far as I'm concerned) combination of dingy, post-industrial Chiquita and thoughtfully selected craft beers. Also, there are no TV's, which makes it a bad place to watch 'the game', but a great place for a conversation. Gold Fish crackers available for a nominal fee; you can bring in pizza from Falbo Bro.'s.
