Chock full of locals, no pretension, cash only dive bar. YES.
I've come here as a group of two and as a group of fifteen - finding space has never proven to be a problem. Yeah, you might have to talk over the cackle of the group of sauced-up soccer moms nearby, but big deal. The drinks are cheap and, as Tarah mentions, cocktails are pint-sized. That alone should have you turning back to warm a barstool.
There's a jukebox, Buck Hunter, televisions, and other bar games to keep you occupied if your company is unpleasant. Otherwise, there are two rooms of seating and the tables are cleared of empty glasses quite frequently making this an ideal establishment to linger over a couple of pints.
