Pretty much your average sports bar, but their $1 shrimp tacos every Tuesday are what keeps bringing us back. That and the fact that they always have Red Sox games on (or put them on when I ask nicely).
It's a good place to hang out in a casual atmosphere, with no frills. Don't expect anything to fancy, although they have a pretty substantial menu.
You kind of get the feeling when you walk in that everyone is a regular (Cheers), and that you'll get strange looks for being an intruder, but everyone is always pleasant and we've been back several times.
