For four days, the Royal Hospital gardens in Chelsea are turned over to a very British mixture of county folk in their red cords and best hats, Londoners drawn by the glitz and glamour and a sprinkling of celebrities and royalty.

If you’re one of the thousands turning up this year, hoping for a glimpse of the venerable Alan Titchmarsh or merely seeking inspiration from one of the many show gardens, you’ll be wanting somewhere to fortify yourself before or after your trip.

Here’s Hot Dinners’ pick of the London restaurants offering something special for diners during Chelsea Flower Week

Champagne tea at Peter Jones

Barely a ten minute walk from the show, Peter Jones is putting on a Chelsea Flower show tea with Orange and Meringue Cupcakes with Violets, mini Elderflower Scones and a selection of Sandwiches for £9.50. Best of all, if you're an RHS member you get a free glass of champagne when ordering either the tea or one of their three special desserts (see picture) crystallised rose petals, raspberry and blueberry syllabub, baked custard tart with nasturtiums or lavender Cambridge burnt cream - all £3.50.
