This Berkeley institution always has a good selection of beer on tap - and as much free popcorn as you can eat! Unfortunately, that is the only food they serve, but they don't mind you bringing your own or ordering a pizza to be delivered.
There are six dart board lanes in the back, along with a few large tables for bigger groups. They host trivia nights (and dart tournaments), have a stack of board games on hand, and have no problem with you bringing your own backgammon or Trival Pursuit game in, either, if you so desire.
All in all, a very comfortable place to have a beer (or two) and hang out.
