"Mauro Colagreco's one-star Whitehall room lists 70 British vegetables before any protein. Book the £125 tasting to impress clients."
About Mauro Colagreco at Raffles London
Mauro Colagreco lists more than seventy British fruits and vegetables on his menu before he names a single piece of fish or meat. That ordering is the point. The Argentine-Italian chef behind Mirazur, long ranked the world's best restaurant, opened his London room inside The OWO on Whitehall when the old War Office became Raffles London in 2023, and it took its first Michelin star in the 2025 edition. The plant produce comes first because Colagreco is a UNESCO Goodwill Ambassador for Biodiversity and grows much of what he cooks. Tasting menus start at £125, with a £65 lunch as the gentler entry.
The Kitchen
Mauro Colagreco built his name at Mirazur in Menton, which topped the World's 50 Best ranking in 2019 and holds three Michelin stars. His Whitehall kitchen, opened inside Raffles London at The OWO, won its first star in the 2025 Michelin Guide. The cooking is technical and quietly precise, organised around the garden rather than the protein: the menu prints over seventy British fruits and vegetables ahead of any fish or meat, a structure that reflects his UNESCO biodiversity role.
The tasting runs £125 at dinner, with a £65 lunch and wine flights from £125 up to a £500 prestige route. Signature plates lean on the produce: a beetroot cooked in salt crust and dressed with caviar, and the marble-patterned vegetable tarts that became a Colagreco signature at Mirazur. Fish and game appear, but as guests of the vegetables, not the headline. Bread and butter alone justify the seat. For the wider field of London fine dining at this level, see the London dining guide and the room's neighbours at Alain Ducasse at The Dorchester.
The Room
The room sits inside a Grade II*-listed Edwardian landmark, the former War Office, and the restraint shows: marble, low brass light, tables spaced for private conversation rather than elbows. The sound level is a soft hum, never loud, which is why deals get done here. Seating runs to about sixty across the dining room and a separate bar. Dress is smart and jackets are encouraged at dinner; trainers and sportswear read wrong in this room. Service is formal, French in cadence, and well drilled. Ask for a table away from the pass if you want the quietest corner.
Best for Impressing Clients
Book this room to impress clients because the address does half the work, the soft acoustics let a table of six actually talk, and the vegetable-led menu reads as serious without the theatre that distracts from business. Take the £125 tasting, hand the wine choice to the sommelier, and let the £500 route appear only if the client reaches for it. The Edwardian setting and Michelin star signal intent without a word. For the same crowd in a private setting, the close-a-deal shortlist and the wider impress-clients guide rank more London options.
Not for
Not for a casual or budget dinner. Dinner is a £125 set tasting with no à la carte, the pace is slow and formal, and a vegetable-forward menu will frustrate anyone hunting a steak.
Frequently Asked
Is Mauro Colagreco at Raffles London worth it?
Yes, if you want serious cooking in one of London's grandest new rooms. The kitchen earned a Michelin star in 2025 under a chef whose Menton flagship, Mirazur, was once the world's best restaurant. At £125 the dinner tasting is not cheap, but the produce-first menu and the OWO setting deliver. Budget-minded diners should take the £65 lunch instead.
How hard is it to book Mauro Colagreco at Raffles London?
Dinner needs three to four weeks of notice, more for Thursday to Saturday. Book direct through Raffles London or OpenTable. The £65 set lunch is far easier to land, often within a week, and is the smartest way to try the kitchen before committing to the full dinner tasting. Tables release on a rolling window, so check midweek mornings.
What is the dress code at Mauro Colagreco at Raffles London?
Smart, with jackets encouraged for men at dinner. The room sits inside the restored War Office and the tone is formal; collared shirts, tailored trousers and proper shoes fit. Trainers, sportswear and shorts will feel out of place. Lunch is marginally more relaxed but still leans smart.
What is the average meal price at Mauro Colagreco at Raffles London?
The dinner tasting is £125 per person, before wine, service and extras. A £65 lunch menu offers a lighter spend. Wine pairings start at £125 and rise to a £500 prestige route, so a full dinner with pairings runs comfortably past £300 a head. Cocktails in the adjoining bar add to that.
What should I order at Mauro Colagreco at Raffles London?
Take the tasting menu and let the vegetables lead: the salt-baked beetroot with caviar and the marbled vegetable tart are the dishes that carry Colagreco's signature from Mirazur. For wine, the £125 exploration flight tracks the menu well; the £500 route is for a client who signals they want it. Do not skip the bread and butter.
