A research vessel went out on a routine deep-space mission and lost contact with home. What came back is not the crew that left.
On October 31st, you arrive as a witness to the aftermath. The room is the wreckage, half-lit by failing emergency systems, littered with the evidence of whatever happened onboard. The story doesn't sit still on a wall. It moves through the crowd around you.
Come in an "Interstellar Nightmare" costume, out of space meets monsters. Got a different idea? Impress us with it. Every costume is in the running for the contest.
Came back from the dark half turned.

Enter The ChampionshipA food and drink experience set aside for VIP ticket holders to close out the night.
Arched, backlit display nooks, dark stone floors, moody lounge lighting. O-Bar already reads elevated and a little theatrical before a single set piece goes up, which is why the wreckage feels at home here.
An intimate, invite-only night on O-Bar and the adjoining patio.
