I've come here every time I visit Vegas. The place gets pretty packed so be prepared to be rubbing shoulders with people all night. The dress code for guys isn't that strict [I've never had an issue] but you have to look essentially clean with a collar shirt and fashion forward, the usual nightclub attire. I always buy a ticket beforehand on the Hakkasan website since that's cheapest price a guy can get in. I don't sign up for guest list since I don't want to start lining up super early not knowing if I would have to pay or not and I would rather pregame and not be rushed to get ready. There are two floors where the main floor plays your typical progressive house and the ling ling club that plays hip hop. Both areas are a good time! Overall, this place is pretty solid for me.
