For the low-intervention winelist, Chelsea has collaborated with her friend and fellow wine-enthusiast Emma Underwood, well-known within hospitality circles for her senior roles at Where The Light Gets In, Stem, Darby's and, most recently, Blue Boar and The Pem. Emma and Chelsea have assembled a list of mostly European wines from land-focused producers, grown on healthy, chemical-free vineyards like that of Brand Brothers in Bockenheim, Germany and sourced from suppliers including Under The Bonnet, Les Caves de Pyrene and Winemakers' Club.

Running to about twenty bins, of which many will be available by the glass – and two on tap – to encourage exploration, the winelist will focus, Emma says, on wines which are “Clean, elegant, fun and fresh.” Designed, like the food menu, to be inviting and accessible, and to help demystify low-intervention wines for those who might be unsure about them, the list will include some familiar grapes like Riesling and Beaujolais, and well-known names like Chateau Musar.

The signature wine will be Tom Shobbrook's hard-to-find Poolside, a refreshing, fruity, light red-to-rosé wine from the Barossa Valley, served chilled and sure to evoke the Australian sunshine. Wine prices will range from £27 to £120 a bottle, and from £7 to £15 by-the-glass.

Specialty coffee is a big part of the daytime drinks offering at Where's Fred's. Chelsea works closely with Origin Coffee Roasters, who source mainly direct-trade and know the story behind the coffee growers and farms, the same ethos as applied by Chelsea and Emma to the sourcing of wines. This quality coffee will also be used in Espresso Martinis by night. Throughout the first week of opening, all specialty coffees will be available for just £1 each.

Occupying the 750-square-foot ground floor of one of the beautifully-restored townhouses which make up Frederick's Place – owned by the Mercers' Company – by day Where's Fred's will be flooded with natural light from tall front windows, a long skylight and a central lightwell. At night, a striking neon, surrounded by an installation of Chelsea's favourite Native Australian flowers by talented florist Izabela Davi, will gently illuminate the room.

Chelsea has conceived the design of the space, realised by Block1: Design, from the exposed-brick walls retained from the renovation – which inspired the overall colour-palette – and the banquette seating, right through to the La Marzocco Modbar espresso taps in the bar area into which guests will step as they open the imposing black door at 7 Frederick's Place.

Says Chelsea of her vision for Where's Fred's, “Where's Fred's is an evolution of the things District does so well for daytime – those easy, satisfying brunch dishes that everyone loves, and seriously good coffee – with the addition for evening of great classic cocktails, sociable, shareable food, and of course amazing natural wines.”

“As soon as I was shown this magical site by the Mercers' Company, I knew that I wanted to do something special with it. Frederick's Place is a charming location that you would mostly find by word-of-mouth; it feels hidden away but is right in the heart of the Square Mile.”

“There's nowhere quite like Where's Fred's in the City of London, and I hope that it will quickly become part of the fabric of the community for workers, residents and visitors alike. Everyone's welcome at Where's Fred's!”
