This month, The Happy Motel and The Mill harness the power of outer space to bring you something entirely extraordinary – a full moon cocktail party held in a glass-domed conservatory, served with extra art and dinner.

Space is great. Great food is great. Good wine is also great. Art is ace.

Given all that, and the existence of the Adelaide Botanic Garden’s Bicentennial Conservatory (a giant hothouse full of tropical plants topped with a domed glass roof) right in the city, it is hard to understand why they haven’t been combined into a party before.

Always here to fill a niche when it’s needed, the guys from The Happy Motel and the ladies from The Mill are collaborating on an event that brings all of the above together.

On the nights of Friday July 31 and Saturday August 1, in celebration of the blue moon, they will open the Bicentennial Conservatory to 120 ticket holders who will be dipped into an immersive art experience called ATLAS, fed a grazing dinner, plied with wine and cocktails and enticed to dance by a series of djs before being asked to participate in (or at least try to enjoy) moon-themed karaoke.

Inspired by the aesthetic of World Trade Fairs, the collaboration came about after the Botanic Gardens approached Amber Cronin and Erin Fowler of The Mill to curate a SALA exhibition in the Conservatory. Having set in motion the wheels of ATLAS – a cinema and soundscape work produced by six artists – they invited The Happy Motel into the fold to develop the event.

“I’ve wanted to do something in that space forever,” says Happy Motelier Jordan Jeavons. “When it’s the full moon in the conservatory, the light from the moon actually illuminates the whole space, so that will be beautiful.”

“The idea is there is all these different elements going on – music, theatre, food, drink, expo-like stalls – all sort of based on the way World Trade Fairs from the past worked, but with an emphasis on the future rather than what’s already happening.”

Shrouded in a good deal of mystery (as all the best things are) there are still some things of which we can be certain. Pink Moon Saloon – the new bar from those behind Clever Little Tailor – will be providing the cocktails, making Nebula Deluxe one of the very first places punters will be able to try their wares ahead of their opening later this year.
