Have to say last night's groove sess was a blast. The lively, hipster bar sets as a scrim on the rooftop features a DJ and a medium sized dance floor with a bar overlooking Fremont and 6th.
Downstairs is a dark and swanky with a large bar with foxy old fashioned dish and bulb lighting. Ample seating throughout.
There's a "secret" room that you can get the password for ahead of time. It's poised as a fun take on a speakeasy. We did not go in, but sounds cool to try out sometime.
Commonwealth is absolutely that cool, hipster vibe in the Container Park area that is a welcome venue in LV in my opinion, opposite the lame casino scene.
