Plan a visit to Wiltons London on Jermyn Street: British seafood and game, oyster bar, dress code, opening hours and official booking links.
Wiltons London is a British seafood and game restaurant at 55 Jermyn Street, St James’s. Its official website highlights oysters, an oyster bar and a carving trolley. For anyone planning to dine there, the dress code is an important practical detail: gentlemen are asked not to wear short-sleeved shirts, shorts, open-toed shoes, sportswear, graphic T-shirts or hooded tops.
Wiltons traces its origins to 1742, when George William Wilton opened a shellfish mongers close to Haymarket. The business is still trading more than 280 years later, now at 55 Jermyn Street, St James’s, London SW1Y 6LX.
That distinction matters: Haymarket is the location of its beginnings, while Jermyn Street is the address to use for a visit today. The supplied history does not establish when the restaurant moved to its current premises.
The official Wiltons website provides its history, location and contact details.
British seafood and game define Wiltons’ stated focus. The official site gives particular prominence to oysters and lists an Oyster Bar and The Carving Trolley alongside its menus.
These are useful pointers to the restaurant’s offering, but the supplied source does not include current dishes, oyster varieties, trolley selections or prices. It therefore cannot support a specific dish recommendation or a reliable meal budget.
Planning recommendation: use the Menus section of the official website to review the current offering before reserving. If a particular seafood or game dish is central to your plans, confirm its availability directly rather than assuming it will be served on your chosen date.
The published dress code asks that gentlemen do not wear:
The supplied wording does not state that a jacket or tie is required. It also does not give a separate dress code for women. Neither omission should be treated as a complete answer to every clothing question.
Practical recommendation: for gentlemen, a long-sleeved shirt, trousers and closed-toe shoes are a straightforward starting point that avoids the named exclusions. If you are unsure about an outfit, consult Wiltons’ official contact details before visiting.
The supplied official website text lists these service times:
Last-seating times are not stated closing times. The supplied schedule does not list Saturday lunch.
Planning recommendation: check the current schedule and availability through the official reservation link on Wiltons’ website. The site also has a Private Dining section for enquiries about that option.
Wiltons is relevant to an itinerary focused on British seafood, oysters or long-established London restaurants. Match your plans to its published service schedule and dress restrictions rather than assuming you can visit at any time or in casual sightseeing clothes.
