I had a pretty great time at Cask Republic right in downtown on Summer St. Coalhouse Pizza is good food and beer too, but a bit outta downtown.
Go to Half Full brewery tonight for their Open House (5-8...I think). For $15 you will get unlimited pours and its a very chill environment. They posted that they will have Rum Pumpkin, Pumpkin, Peach Wheat, an APA among other offerings tonight. Its not the world's greatest beer, but its a hell of a value and the people are all very nice. Otherwise I echo Coalhouse or Cask as your other best options for good brews.
