10 Union Street

For an intimate dinner that leaves a lasting impression, the Atrium at 10 Union Street is in a class of its own. Comfortably can accommodate 80 guests for a seated dinner and 200 guests for standing reception, this is one of SE1's most breathtaking private spaces -a soaring, light-filled room that transforms beautifully from day to evening. As the natural daylight fades, the Atrium takes on a warm, atmospheric quality that no ballroom or hotel dining suite can replicate. The architecture does the talking -elegant, characterful, and genuinely unique. Whether you are hosting a corporate dinner, a client entertainment evening, an awards celebration, or a milestone private occasion, the Atrium creates the kind of setting where conversation flows and guests linger long after dessert. The space is equipped with microphone facilities, ensuring that speeches, toasts, and presentations land with clarity and confidence - a thoughtful touch that elevates the experience for both host and guest alike. Pair the space with our in-house catering team, who will work with you to craft a menu that reflects the occasion, and you have everything you need for a truly memorable evening - all under one roof, steps from London Bridge and Borough Market. An intimate, iconic space for dinners that deserve to be remembered.
