Scenesters, models and foodies arrived en masse to cheer on Susan Jane White and her new cookery book The Extra Virgin Kitchen.
Author Eliza Pakenham and director Conor Horgan tucked into beetroot bon bons and raw chocolate pots, while artist Fergal McCarthy and chef Domini Kemp milled about the room.
Lithe and lean models January Russell and Claire Tracey discussed life outside the elite fashion world.
"I'm a model-slash-dog groomer," Ms Tracey said.
"There aren't that many of us around. It's a bit dirty and not that glamorous – a bit like the modelling world actually."
The fabulously named January Russell, meanwhile, is getting up, close and personal with Love/Hate stars Killian Scott and Peter Coonan on the set of The Traders.
"I'm assisting in the wardrobe department but want to get into TV presenting and acting," she said.
"I have a lot of fingers in a lot of pies."
We wouldn't tell too many people that.
Guests slugged back bottles of fizzy green tea by Dublin Kombucha which had been locally brewed by Dubliner Laura Murphy. "I learnt to make it when I was living in Brooklyn; a Kombucha Master showed me the tricks of the trade. But I can't tell you his name – it's shrouded in mystery," she laughed.
The room was buzzing and Susan Jane stood in the corner frantically signing books. "I've had a smashing night," she said. "I wanted to show that healthy cooking doesn't have to be boring, or dominated by neurotic celebrities." Take note, Gwyneth Paltrow.
