45 Jermyn St.

To keep a caviar trolley going over many years is one thing; to build it into Fortnum & Mason’s 21st-century restaurant and cocktail bar is quite another. That oscietra- and beluga-loaded vehicle is just one luxury on offer here; other treats include potato, jamón and a fried duck egg for breakfast, a trio of Alba truffle dishes and a boozy ice-cream float for afters. The carte majors in ideas that feel safe, but indulgent: pine-nut crusted scallops with bottarga butter, perhaps, followed by lamb belly with leek and potato dauphinoise, plus something cold in a coupe for dessert (brandy cherries, cinnamon and vanilla ice cream, for instance). This venue used to be The Fountain, but the new look is bolder, with a line of tomato-red stools at the long marble bar and plenty for their occupants to drink. Everything is lovely – “as always with Fortnum’s”.

A celebration of old-school glamour with a modern London twist, 45 Jermyn St. is Fortnum & Mason’s sophisticated restaurant and cocktail bar in the heart of St. James’s. From its striking orange banquettes to its impeccable service, this is a place where dining is as much about the experience as it is about the food.

As the restaurant venture of Fortnum & Mason, 45 Jermyn St. carries forward the same dedication to quality and excellence that has defined the brand since 1707. Located just moments from the flagship store on Piccadilly, the restaurant offers an elegant yet welcoming setting where classic hospitality meets contemporary flair. Open every day from breakfast through to dinner, it provides a carefully curated menu that blends timeless British favourites with global inspiration, ensuring that every dish is both comforting and exciting.

The menu is as refined as its surroundings. Start with the Piccadilly smoked salmon with soda bread, indulge in the Cornish mackerel and caviar tacos, or opt for a true Fortnum’s classic - the rich, perfectly balanced Welsh Rarebit. For the main event, meat lovers will relish the Beef Wellington served with dauphinoise potatoes, green beans, and peppercorn sauce, while the Native Breed Cumbrian rib eye with chips and Béarnaise offers a masterclass in steak perfection. Those looking for something lighter can enjoy the monkfish with St Austell Bay mussels in a champagne butter sauce, or the hake with wild mushroom and butter bean fricassée. Sides like peas and leeks, roasted beetroot with horseradish, and kale with ginger and almond dressing ensure there’s something for everyone.

Alongside the menu, the cocktail list is just as impressive, offering carefully crafted drinks that nod to both classic mixology and contemporary innovation. Whether you’re stopping by for a leisurely meal, a celebratory dinner, or a pre-theatre cocktail, 45 Jermyn St. delivers an experience that’s as effortlessly chic as its surroundings - bringing back the golden age of glamour and service in the heart of London.
