Casual vibe. They are serious about the beer and have a great selection. They a few tasty stout options, which I love. Bartenders care about this and will give you all the details you could ever want.
Patrons vary widely in age and type. A female friend was waiting alone for a few minutes, and she mentioned that she was accosted by 3 different men crudely attempting to initiate conversation. It was probably just her being hot and wrong place, wrong time.
Good patio vibes. It gets a bit shady at night. One time there was a racoon that did not care about being surrounded by humans. It proceeded to rifle through the garbage can that was outside and then saunter off past our table with some scraps of food.
Conclusion: Excellent casual option for quality beers
