This place frequently appears on Top Ten lists, and it would deserve to be there if those lists tracked the best small/neighborhood pubs.
They only serve beer, which is not a problem if you know it going in. Their selection of regional and craft brews will certainly keep you and your party satisfied for the entire evening. The bartenders are extremely helpful and friendly, leaning in and making you and your party feel as their personal guests.
The down side is that it is extremely small, and out of the way for most residents of the Valley. If you don't mind the claustrophobic setting (which doesn't matter once you find a place to sit), and driving to a strip mall, then this place is a great spot to hang and enjoy awesome beer.
