The signature fish dish. Fresh cod fillet in their signature batter, fried to golden perfection. Crispy exterior gives way to flaky, moist fish. Diners consistently praise the quality and freshness. Available grilled or fried, with options for different batters (gluten-free, matzo meal, panko).
Tips from diners
The dine-in price is double the takeaway (£18 vs £11), so if budget matters, order takeaway and eat it nearby or at home.
Ask for chunky chips rather than other sides—they're the classic pairing and the best on offer.
Traditional favourite with fresh haddock fillet in their signature batter, fried until golden. Slightly more delicate flavor than cod. Available with choice of sides: chips, new potatoes, or mixed salad. Reviewers note it's slightly lighter than the cod.
Tips from diners
Slightly more delicate than cod—try both to find your preference.
A classic British accompaniment to fish and chips. Smooth, creamy, and subtly flavored. More interesting than it sounds—adds texture and breaks up the richness of the fried fish.
Tips from diners
Order this as a side with your fish—it's the traditional combination.
A traditional British starter or side dish. Tiny whole fish, lightly battered and fried until golden and crispy. You eat them whole—they're delicate and crunchy. Less common on modern menus but a specialty here.
Tips from diners
A crispy, savory start. Squeeze lemon over them before eating.
A French-style mussel dish with fresh mussels in a creamy white wine and garlic sauce. More sophisticated than the fish and chips, but showcasing the restaurant's commitment to fresh seafood. Reviewers describe the white wine sauce as addictive.
Tips from diners
Pairs beautifully with one of their white wines from the comprehensive wine list.
The Seashell began as a small fish bar after World War I before being formally established as The Sea Shell in 1964 and expanded by John Faulkner in 1971. After a devastating fire in 2009, the restaurant was rebuilt and reopened, retaining its legendary status. Chef Alain Ducasse has called it 'the best fish and chips in London.' The fish is North-East Atlantic, line-caught, and hand-battered fresh daily.
Significant price difference between dine-in and takeaway (£18 vs £11 for the same fish). Both are good quality—takeaway is better value if you're flexible.
Bookings available via OpenTable. Weekends and evening peak times can fill up—reserve ahead if you want a guaranteed table.
Located in Marylebone, near Regent's Park, Oxford Street, and Abbey Road Studios. A destination rather than a passing spot, but worth the trip for serious fish and chips devotees.
The wine list is comprehensive and well-curated—staff are knowledgeable about pairings with seafood.
Gluten-free, matzo meal, and panko batter options available for the fish. Ask your server about other dietary adjustments.
