Also known as the Empire Events Center, the Empire is a hip nightclub in Midtown. Wednesdays are college nights, where you can get $2 off if you flash your UCD/Sac State/or Los Rios Community College district ID card. Their dress code is as follows-

A button-up collard shirt is required, No T-Shirts, No Polos, No sports attire, No Logos, No Baggy or Saggy clothing of any kind, No hiking style boots (Timberline, Lugz, etc), No sneakers (unless otherwise stated on event info), hats, etc.—(taken from their website).

If you're feeling cheap, a Sacramento Regional Transit light rail station is located just behind it, although the last train arrives/leaves at 11:31pm, which is about the time the place really starts to get bumpin'.
