/ About

Mosimann's occupies a former 1830 Scottish Presbyterian church on West Halkin Street in Belgravia, converted in 1988 by Anton Mosimann into one of London's most revered private dining clubs. The double-height nave retains the building's original stained-glass windows and soaring arches; the mezzanine Balcony Bar sits above, serving as gateway to seven individually conceived private dining rooms, each sponsored and designed by a distinguished luxury house.

The rooms range from the Montblanc Room (reportedly the world's smallest private dining room, designed for two) up through intimate chef's tables, crystal-laden salons, and library-style semi-private spaces, to the Casa Luiza Room at the top of the belfry spiral staircase: a 50-seat space with vaulted arches and an original oil-painted floor by London artist Lauren Mele. The Davidoff Room on the second floor opens onto a private terrace, while the Lanson Library adjoins the main restaurant and can be screened off or combined for exclusive-hire gatherings.

The club serves cuisine naturelle — a philosophy centred on the integrity of exceptional produce. For private events, every room carries a late licence and in-house catering; the main restaurant and Lanson Library together accommodate up to 110 for a seated dinner, or the whole building for a standing reception of up to 200.
