The atmosphere INSIDE deserves a 4, outside deserves a 2.
The beers themselves were a solid 3 stars, nothing super great but nothing super terrible. The Turncoat gin-aged IPA was outstanding, though. Didn't taste like an IPA, but it was super smooth and mellow.
Banger is a decent place to go if you want to hear yourself think and get away from the hubbub of Fremont, but the beers are decent at best.
