The "OAK" in this nightclub's name is an acronym for "Of A Kind," and, indeed, it's darker and louder than just about any other dance club in Vegas. And on a good night, sexy revelers are packed in and pumping like you wouldn't believe. Two separate rooms each have a bar and DJ (music styles change weekly). An animal theme is prevalent throughout, with zebra stripes, jaguar spots, and other patterns visible from just about every angle. The influence is subtle, but don't be surprised if your inner beast bursts out.
