Fifty-five stories above the Strip, Ghostbar throws its Halloween party on the kind of night when the whole valley glitters below you. Doors open early with Ketel One Vodka cocktails at a discounted price for the first couple hours, giving everyone time to settle in before DJ J-Bray takes over the booth and keeps the dance floor moving through the night. The outdoor patio remains the real draw here, wind at that altitude, the Strip's lights stretched out in every direction, and the city looking small enough to hold in your hand.

Costumes are the whole point of the evening, with a grand prize contest kicking off mid-party that puts real money on the line for whoever brings the best look. Expect the usual mix of horror, camp, and elaborate group costumes competing under the lights, with the panoramic backdrop making every photo look better than it probably deserves to. This one's 21 and up, and given the venue's reputation, dressing to impress seems like the unspoken dress code even beyond the contest itself.
