28-34 St. Martin's Court, London WC2N 4AL

Often seen as both the theatregoers and the actors' port of call post-theatre, Sheekeys is a London institution. It remains best known for its seafood, including an incredible fish pie which is still one of the best in London. A must-visit for every Londoner and notably great for counter dining, as well as its extensive, covered terrace.

32 Henrietta St, Covent Garden, London WC2E 8NA

The Oystermen originally started up as an oyster-shucking pop-up but their Covent Garden restaurant is so much more. It started tiny before they acquired the next-door space and doubled the size. But all along, they've been serving up excellent seafood from a menu that depends on the catch of the day.

National Portrait Gallery, St Martin’s Pl, London WC2H 0HE

Right at the top of the revamped National Portrait Gallery, this is the main restaurant with excellent views across London. In charge of the food is top Irish chef Richard Corrigan (Bentley's) who has brought with him a modern approach to European cooking with plenty of seafood on offer too.

37 Bedford Street, London WC2E 9EN

Thirty7 comes from the Oystermen (Matt Lovell & Rob Hampton), and is just around the corner from their first Covent Garden restaurant. They describe the restaurant as a neighbourhood restaurant and bar which goes beyond the seafood focus of before (although you will find oysters on the menu). Make sure to have the cheddar beignets and also pop down to the excellent bar downstairs.
