This little bar at the Hipster section of Fremont Street (past all the crazy) is awesome! Gorgeous interior with wood accents and dark chandeliers give it a Gothic look while screaming speakeasy at the same time. The drinks are very creative (try "The Hot Mess"). Very friendly bar staff (although it was empty when I was in there and perhaps that is why I received so much attention)
Place seems like it most likely attracts more locals than it does tourists. I would come back here in a heart beat if I was ever caught dead in Fremont.
