What 123V does

123V is a London-based plant-based restaurant group founded by chef Alexis Gauthier, operating two distinct venues in central London: the refined 123V Browns at 39 Brook Street in Mayfair (adjacent to Claridges Hotel), and the more casual 123V Bakery/Studio Gauthier in the BFI building on Stephen Street, Tottenham Court Road. The company pioneered the "Garden Sushi" concept — a 100% plant-based interpretation of sushi built on proprietary ingredient formulations, including vegan tuna (pressed tapioca starch, flaxseed oil, paprika, marinated in soy, nori and kelp) and vegan prawns (potato starch, kelp, wheat fibre, soy protein powder).

Core offerings span à la carte Garden Sushi, bottomless sushi at £36, a daily-changing lunch bento at £14, a luxury Nuggets & Caviar experience at £35, hand-written gift vouchers delivered worldwide, and a bakery/café line serving coffee, pastries, focaccia, sandwiches, and self-serve salads. The business operates a direct-to-consumer model with dine-in service, online reservations, private event hire (including a private garden courtyard and function room), and local bakery delivery for office catering. Its primary customer base is London-based diners and tourists seeking premium plant-based dining, with secondary segments in private events/corporate functions and corporate bakery delivery clients. The company is independently owned, with no disclosed external investment, parent entity, or institutional backing.

Broad incumbents

• Itsu: Itsu is a UK sushi and Asian chain with restaurants and grocery products. It is a broad incumbent because it competes in the same sushi category and London locations, but at fast-casual price points rather than 123V's premium vegan positioning.
• YO! Sushi: YO! Sushi is a UK sushi restaurant chain with a conveyor-belt model. It is a broad incumbent because it competes for sushi occasions in the UK but at significantly lower price points and without a vegan-native menu.
• Wagamama: Wagamama is a UK-wide Japanese-inspired noodle chain. It is a broad incumbent because it overlaps with 123V on Japanese cuisine and UK dine-in trade but operates at far larger scale and lower price points with a non-vegan default menu.
• By Chloe: By Chloe is a plant-based fast-casual restaurant brand originating in the US. It is a broad incumbent in the plant-based dining space because it competes on vegan positioning, though its menu is not sushi-focused and its UK footprint is limited.

Direct peers

• Studio Gauthier: Studio Gauthier is another Alexis Gauthier venue offering relaxed plant-based dining and bottomless sushi, and houses the 123V Bakery. It is the most directly comparable venue to 123V because of shared chef, overlapping menu, and co-located bakery/delivery operations.
• Vanilla Black: Vanilla Black is a London vegetarian fine-dining restaurant. It is a direct peer because it competes for the same upscale vegetarian/vegan diner in central London with tasting menus and refined plating.
• Mildreds: Mildreds is a long-running London vegetarian and vegan restaurant group with multiple sites. It is a direct peer because it targets the same plant-based diner in central London at comparable price points with similar lunch and dinner menus.
• Farmacy: Farmacy is a London plant-based restaurant in Notting Hill. It is a direct peer because it serves an upscale plant-based menu targeting similar health- and ethics-conscious London diners with comparable price points.
• The Gate: The Gate is a London vegetarian and vegan restaurant group with multiple sites. Comparable to 123V because it shares the plant-based positioning, central London trade, and similar price points for lunch and dinner.
• Gauthier Soho: Gauthier Soho is the same founder's plant-based fine-dining restaurant in central London. It is the closest peer because it shares owner, culinary philosophy, customer base, and pricing tier, and operates a directly comparable plant-based tasting menu concept.
