Every Las Vegas nightclub begins with one negotiation: the long line. We recommend calling ahead to reserve bottle service. The $350-plus price tag might seem outrageous, but factor in guaranteed seating and not having to deal with the clamor at the bar, and it starts sounding reasonable. Otherwise, getting on the list is a matter of who you know or how well you sweet-talk. Ask your cabdriver if he has any line passes, or chat with your concierge. On weekends, the scene gets going around midnight and winds down around 5 a.m. Some clubs are open on select weekday nights, so call for hours and cover chargesexpect to pay $10 to upwards of $100.
