Chelsea in Bloom is London’s largest free flower festival, running from 18 to 24 May 2026 alongside the RHS Chelsea Flower Show. Now in its 21st year, the festival sees more than 140 businesses across Chelsea transform their shopfronts with spectacular floral displays. This year’s theme, ‘Out of This World’, takes inspiration from space travel, astrology and celestial symbolism. Colbert, on Sloane Square, sits at the heart of the festival route.

Yes. Colbert is participating in Chelsea in Bloom 2026 with a seasonal floral display and a special menu. As one of the neighbourhood’s founding all-day restaurants, we welcome guests throughout the festival week for breakfast, lunch, and dinner.

Colbert is located at 50-52 Sloane Square, SW1W 8AX, directly on Sloane Square which is the central hub of the Chelsea in Bloom festival. The nearest tube station is Sloane Square (District and Circle lines), a short walk from the restaurant. The majority of the festival’s major installations begin here, making Colbert a natural starting or finishing point for the walk.

We recommend booking in advance, particularly for the evenings of 18-24 May 2026 when Chelsea is at its busiest. Reservations can be made online or by calling 020 7730 2804. We hold a number of tables for walk-ins each day, though availability during the festival week cannot be guaranteed. Please note we are unable to take reservations for coffee or drinks only.

Yes, during the festival week, our kitchen will be serving a Gariguette Strawberry & Elderflower Pavlova. Our all-day menu is available from early morning through to late evening throughout the week, taking in Parisian café classics alongside weekly specials from Head Chef Sascha Rieb. Whether you are looking for breakfast before the displays or dinner after the flower show, Colbert is open seven days a week.

Colbert is a ten-minute walk from the Royal Hospital Chelsea, home of the RHS Chelsea Flower Show (19-23 May 2026). Open from 8am until late, the restaurant offers a base for visitors attending the show, whether for a morning coffee before the gates open or a relaxed dinner afterwards. Reservations are advised during show week.
