One O One

Knightsbridge has many hotel dining rooms that trade on postcode rather than plate, but One O One at the Sheraton Park Tower has built its reputation on a more specific proposition: a seafood-focused menu with French technique at its core, overseen by chef Pascal Proyart, who trained at Le Divellec in Paris before bringing that tradition to SW1. The kitchen's orientation toward fish and shellfish is not a loose theme but a structural commitment, with seabass given its own dedicated menu section alongside oysters, halibut, tuna, and king crab. Proyart's Brittany roots inform both the sourcing instincts and the cooking register. The style sits firmly in the polished fine-dining bracket: dishes are composed with decorative care, the room carries a marine aesthetic through blue furnishings and oyster motifs, and the overall feel is that of a serious hotel restaurant rather than a casual neighbourhood fish counter. Reviewers have pointed to the provenance of the seafood as a particular strength, and the pricing reflects that positioning: starters have been documented in the £14–£19 range, mains in the £23–£29 range, with smaller tasting-format dishes running from £38 upward. The Knightsbridge address places One O One within easy reach of the major hotels along Brompton Road and the broader luxury corridor that runs toward Hyde Park Corner. For visitors already staying in the area, it functions as a credible destination in its own right rather than a default fallback. The cooking has a clear point of view, the seafood sourcing is taken seriously, and the French-leaning technique gives the menu more coherence than the broader category of "hotel seafood restaurant" might suggest.
