Roka fits in beautifully with its Fitzrovia neighbors. There's something elegant almost Edwardian to its atmosphere, and you wouldn't be surprised to find London A-listers drifting through its doors. It's sleek and welcoming, and its offerings of fish and shellfish is near impossible to rival. Roka's Premium Tasting Menu will get you delicate treasures like yellowtail sashimi with yuzu-truffle dressing and naka kaki Irish oysters with ponzu and chili daikon. Or for something more indulgent, try the rice hot pot with king crab and wasabi tobiko. It's a different vibe entirely from the new ramen pop-ups and the financial district's in-and-out sushi counters. It's seasonal and stylish, and the perfect afternoon indulgence.
Recommended for Seafood because: It uses seafood beautifully to produce traditional dishes in a stylish, modern atmosphere.
Arianna's expert tip: Rest your feet in Roka's famous Shochu Lounge. The bustling basement-level cocktail bar is a perfect counterpart to the sophistication upstairs.
Sitting atop the South Place Hotel, Angler makes apparent early on its elegantly versatile nature. With "sustainable seafood from British waters, paired with the best seasonal and local produce", as well as world-renowned sommelier Benoit Allauzen, Angler is a double-hitter, and might just be the wine-enthusiast's seafood paradise. Their tasting menu includes everything from smoked eel to minestrone, and they offer a Sunday BBQ which reinvents the form: mackerel-squid sliders, prawn and pork belly skewers, and Cornish cod goujons. Why not pair with a sleek Sunday cocktail like the Angler "Doctor's Order" which includes Woodford Reserve, lemon, honey, egg white, and cherry bitters? Doctor's orders, after all.
Recommended for Seafood because: It's the full gourmet package – save your take-away lobster roll for another day.
Arianna's expert tip: Keep your map to hand – Moorgate can be a bit of a labyrinth, but Angler is well worth the searching.
Take a Michelin star chef, an intimidatingly swanky location, and a near theatrical take on detail and decor, and you have Umu, one of the shining jewels in Mayfair's menagerie of high-end Japanese luxury restaurants. Head Chef Yoshinori Ishii has been displaying his flair for exquisitely delicate Kyoto-inspired cuisine since taking over at Umu in 2010, and he has curated an experience which will leave both Japanese-food-pedants and poshies in awe. For £45 a set lunch will get you a selection of fresh sashimi with kinshi and shiitake, or go a la carte and try Ibushi smoked "a la minute" with plum-shiso for £28.
Recommended for Seafood because: It applies beautiful innovation to the freshest of the fresh fish and shellfish.
Arianna's expert tip: Stroll through Hyde Park before dinner to catch the always-gorgeous sunset.
Balthazar is not, strictly speaking, a fish restaurant or an oyster bar, but rather a transported New York institution which happens to lord its seafood-mongering talents over the competition with stylish non-effort. It's the definition of gold-plated Old World nostalgia-chic, a gold-lit monument to the early days of New York and London's first metropolitan romance. Try lobster spaghetti for £27 with a full-bodied rosé like Coche-Bizouard Bourgogne Rouge. If you're feeling especially extravagant, try the "Le Balthazar"-sized pleateaux de fruits de mer: lobster, whelks, mussels, dressed crab, langoustine, shrimp, oysters, and ceviche. It's decadence done right, and you'd be advised to come with an appetite.
Recommended for Seafood because: Balthazar does abundance right, with stunning transatlantic elegance and a certain Manhattan charm.
Arianna's expert tip: Try the Balthazar brunch on a Sunday – hazelnut waffles and escargot never made such a perfect pairing.
Trishna's Michelin star was awarded in 2012, a time in which London was in the global spotlight. And indeed there may be no restaurant in London which better represents its spirit: Indian restaurant Trishna presents a terrifically elegant dance of cross-cultural approaches to fresh, sustainable, gorgeously prepared seafood and shellfish, tucked in one of the city's most beloved neighbourhoods. Try a tasting menu, which includes Dorset brown crab with butter, pepper, chilli, and garlic. Or go a la carte and try Trishna's Hariyali bream with green chilli, coriander, and smoked tomato kachumber. There's no better preparation of rich west Asian flavours, and it'll leave seafood enthusiasts bragging for weeks.
Recommended for Seafood because: It's a laid back, layered presentation of Britain's most beloved cuisine.
Arianna's expert tip: Get to Marylebone early for a stroll along its quiet, winding streets.
The Wright Brothers have made seafood many things: sustainable, curated, and very cool. Embedded in Spitalfields Market within a stone's throw of folksy menswear boutiques and the vintage racks, The Wright Brothers seem to have absorbed the identity of the east for their latest addition to their set of restaurants and oyster bars. But all that brassy, stylish veneer hasn't distracted from the Wright Brothers's commitment to taste and sustainability. "By sourcing pacific oyster seed from a hatchery," they explain, "we ensure that our farming is entirely sustainable and we do not deplete any wild stocks. We take out from the marine environment only what we put in." Go for dressed oysters with spring onion mignonette (£10) and deep-fried Peterhead haddock with mushy peas and triple-cooked chips (£18.50).
Recommended for Seafood because: It's the perfect addition to Spitalfields Market and the perfect display of London's fish-loving culture for new visitors.
Arianna's expert tip: If you're staying further west try the Wright Brothers Oyster Bar in Soho.
It's ethical, it's bountiful, it's fresh, and it's delicious. Loch Fyne is without a doubt one of London's strongest seafood restaurants, even though some of their produce has made quite the journey to your table. "Much of the shellfish and smoked fish served in our restaurants still comes direct from the loch," the team behind the restaurant, with locations in Edinburgh, Bath, London, and beyond, explains, "and is delivered so fresh you can taste the fresh spring water that tumbles down from the surrounding mountains when you tuck into a delicious Loch Fyne oyster." Go for a shellfish platter with a whole crab: oysters, king prawns, hot crevettes, Scottish rope-grown mussels, Palourde clams, squid, and langoustines, all for £54.95.
Recommended for Seafood because: Their attention to sustainability is at the heart of Loch Fyne, and yet you'll be focused on nothing but flavor during your visit.
Arianna's expert tip: Be sure to pair your incredible meal with a light white – try a bottle of Ara Estate Pinot Gris for£25.95.
Barrafina offers the kind of food you have to work for. It's virtually impossible to avoid an hour-long queue (the seats barely hit the double digits), and you're likely to be elbow-to-elbow with strangers. But once you've got your first glass tinto, Barrafina's exquisite spirit becomes increasingly exposed. Stunning seafood dishes like octopus with capers (at £9.80) are profound in their simplicity, bringing out clean, startlingly robust flavors. More ambitious dishes like the Pluma Ibérica with confit potatoes showcase the rare culinary gifts of Head Chef Nieves Barragán Mohacho and her team, for a total experience which is dizzying and unforgettable. Barrafina is truly a gift, and absolutely worth the wait.
Recommended for Seafood because: Watching your chef hand-prepare your fresh-caught octopus makes your experience at Barrafina well worth the wait.
Arianna's expert tip: Get there early or late – there are no bookings and few seats, so avoid peak queue times (though you're free to drink prosecco in line)
Part fishmonger, part seafood bar, Prawn On The Lawn manages to be one of the most charming 'holes-in-the-wall' London has to offer, where fresh-from-the-ice scallops, monkfish, squid, langoustine, and of course the eponymous prawns get made in to colourful, delectable small dishes. Blink in Highbury and you could miss it: head downstairs to the 16-seater basement for an intimate dining experience. Try seared tuna with chilli, coriander, spring onion, mirin, and soy for £8.50, or Prawn On The Lawn fruits de mer for £60, which includes crab, prawns, mussels, clams, jumbo prawn, smoked prawns, langoustine, whelks, crevettes, and oysters. It's well worth the jaunt from Islington's beautiful Upper Street, and while you're there you can wander toward less-trodden Canonbury for a pint at The Snooty Fox or a walk around Newington Green.
Recommended for Seafood because: It's as unique as its name, and still a hidden treasure amongst London's seafood mega-names.
Arianna's expert tip: Ask POTL's resident fishmongers for tips when you purchase any of their fresh fish and shellfish. They're a font of insight.
It's part of London's vast culinary mythology, and it feels a bit like stepping back in time to Covent Garden's theatrical heyday. J Sheekey offers a cornucopia of the city's freshest seafood in a darkly lit, brass embellished ambience which is perfect for highbrow romancing or laid back business dealings. Start with scallops in a halfshell with garlic and chilli for £17.50, and move on to a grilled Dover sole with bearnaise for £39.50. All whilst sipping on something fizzy – a Gyéjacquot Brut, perhaps? J Sheekey is the kind of London institution both your grandfather and your hip niece are dying to dine in, so book quick!
Recommended for Seafood because: It's classic west end glam met with unbeatable fresh catches. There's nothing more a hungry London visitor could want.
Arianna's expert tip: For something a little quicker try the infamous J Sheekey Oyster Bar, opened noon til midnight.
