It might not be the dramatic cliffs of Cornwall, where the oysters practically leap from the sea into your loving arms, but London has a huge amount to offer when it comes to seafood. The city hosts some of the most robust fish markets and uses its geography of wharves and tributaries to source those tasty treats that give all the buzzworthy restaurants their stand-out dishes. Fish concoctions are often the stars of London's Michelin star restaurants (the flamed mackerel at Fera at Claridge's? We swoon.), and no trip to London would be complete without sampling England's most prized resource – allergies permitting. Fan of fish and chips, firm in its position as the food of the people? Serious about sashimi, in a city where Japanese is having a long-overdue moment? We're here to guide your way through the high-flying-est luxury spots and the most indulgent secret finds. You can splash out – no pun intended – or go budget, and our picks for London's fish foodie finds always maintain a focus on sustainability and eco-ethics. So get your bib on, your crab cracker out, and remember which one is the fish fork (far right?), because your London seafood journey starts here!
