Seashell of Lisson Grove

The Seashell of Lisson Grove is a fish-and-chip restaurant and takeaway at 49-51 Lisson Grove, Marylebone, London NW1 6UH. The operator traces cooked-fish premises on Lisson Grove to the period after the First World War, says the business took the SeaShell name and moved to the corner of Lisson Grove and Shroton Street in 1964, and records an expansion from 12 to 90 seats in 1971. A fire damaged the restaurant in 2009 and the rebuilt venue reopened in 2010. The archival image shows the exact signed exterior during the 2009 closure and must not imply that the restaurant remains closed. Choose The Seashell for a fish-and-chip meal on a Marylebone route, not as a generic source for every London chippy.

Choose between the restaurant, takeaway and online collection or delivery service before reading prices or planning time. The operator lists cod, haddock, plaice, salmon and sea bass and offers fried, grilled, gluten-free-batter, no-batter, panko and matzo-crumb preparations. It says the fish is halal and that beer is not used in the batter, but those statements do not answer every ingredient or cross-contact question. The rebuilt restaurant includes an art-deco interior, an aquarium and a private dining room, while the takeaway supports a quicker meal. Compared with Rules or St. JOHN, The Seashell is the most direct choice when fish and chips is the target dish; compared with The Orangery, it is not an afternoon-tea setting. Use the exact restaurant or takeaway menu because the formats and prices are not interchangeable.

The operator does not publish a standard meal duration. A takeaway collection and a seated restaurant meal have different time needs, so choose the format first. A restaurant booking requires time for seating, ordering and the selected courses; a takeaway plan still depends on preparation and collection demand and has no guaranteed turnaround in the reviewed source. Keep a margin before a train from Marylebone or a timed attraction, and do not convert the published opening hours into a service-time promise. The private dining room is a separate group format and should be arranged directly rather than treated as normal walk-in seating. Visitors who want fish and chips without crossing London should use The Seashell when Marylebone fits the day; the guide does not claim that a special journey will always be more useful than a verified venue near their existing route.

The Seashell publishes restaurant opening from 12:00 to 22:00 Monday through Saturday and from 12:00 to 19:00 on Sunday. These are the operator's general hours checked on 8 September 2026, not a guarantee of a table, immediate takeaway collection or every fish species. Use the booking route for a seated meal and the live ordering route for collection or delivery. Lunch works with a Marylebone or Regent's Park itinerary; dinner is available later on Monday through Saturday than on Sunday. The source does not establish quiet times, queue lengths or a booking requirement for every visit, so omit those assumptions. Fish is delivered fresh and remains subject to availability according to the operator; check the current menu when cod, haddock, plaice or another specific choice is essential.

The Seashell has no general admission ticket; pay for the restaurant or takeaway order. The live takeaway shop checked on 8 September 2026 listed cod and chips, haddock and chips and plaice and chips at £11 each. Keep those prices attached to takeaway: they are not dine-in prices, a complete meal total or a guarantee for a later date. Restaurant and takeaway menus are presented separately on the operator site, and delivery can add a third commercial path with its own availability. Recheck the correct menu before ordering. The venue's claim that fish is delivered fresh also means a species may be unavailable, so a posted example is not a reservation of that dish. No universal deposit, minimum spend or cancellation rule was established from the reviewed pages; use the booking flow for current terms.

Use 49-51 Lisson Grove, Marylebone, London NW1 6UH as the destination. The restaurant stands near the corner of Lisson Grove and Shroton Street, north-west of the core West End sightseeing area. It fits most naturally with Marylebone station, the western side of Regent's Park or a route already using Lisson Grove. The operator links to a map but does not publish one universal station or walking time, so use a current journey planner from the day's starting point. Confirm whether the plan is restaurant dining, takeaway collection or delivery before setting the final destination. If the rest of the day is in Covent Garden, Kensington or Smithfield, Rules, The Orangery or St. JOHN may avoid a cross-city detour; the page is designed to help choose one meal, not collect all four venues.

Dietary labels require a direct conversation when safety matters. The operator offers gluten-free batter, no-batter, panko and matzo-crumb choices and says its fish is halal because the batter contains no beer, but it does not describe the whole kitchen as allergen-free. Its FAQ tells diners to inform the server about allergies or intolerances and says a full ingredient list is available on request. It also warns that, although staff try to remove bones from filleted fish, every bone cannot be guaranteed absent. Ask about the chosen fish, coating, fryer and cross-contact instead of converting a preparation option into a safety promise. The site says lift and ramp access are available for the restaurant and takeaway and lists accessible toilets. Families are welcomed, with high chairs and baby-changing facilities recorded, but temporary promotions should be rechecked rather than promised.

The Seashell operator pages do not publish a general visitor-photography policy. Ask staff before photographing the art-deco interior, aquarium, kitchen-facing areas or other diners, and do not block the entrance, lift, ramp or service routes. No permission for flash, tripods, commercial work or photography in the private dining room is recorded. The credited reusable image is an exterior photograph of the exact signed premises from 2009, credited to Oxyman under CC BY-SA 2.0. It was taken during the closure after the fire and is therefore archival identity context only. Its shuttered appearance must never be used to claim the restaurant is currently closed, neglected or operating under the same exterior conditions. Current status comes from the operator's live site, not the photograph.
