Founded by a father-daughter duo in Moscow two decades ago, Sumosan has built a reputation around the world as a purveyor of contemporary Japanese cuisine in opulent surroundings. As well as serving the global elite in the Russian capital, Monaco and Dubai, the group keeps London in high-end sushi and sashimi through a newly relocated restaurant in Belgravia. The Sloane Street outpost is discreet enough to meet the needs of A-list celebrities, but if it really is a private event you're hosting, call on the cross-town catering service.
