Igni, by Theo Clench
If we’re being honest, "live-fire cooking" in Mayfair has started to feel a bit... loud. There is too much testosterone, too much scorched earth, and far too many chefs acting as though they’ve personally discovered Prometheus’s secret. We’ve been trapped in an era of culinary machismo where everything is blasted, blackened, and performatively primal.
Then came IGNI.
For me, walking into 12 St. George Street feels like a personal haunting. Years ago, when this site belonged to Wild Honey, it was where I had my very first Michelin-starred experience - an era of starched tablecloths, delicate French technique, and quiet European refinement. The space has undergone quite the evolution since then, most recently housing the smoke-centric Humo.
But IGNI isn't just another addition to London's obsession with the hearth; it feels like an elegant course correction. It is less a barbecue and more a culinary séance, bridging the gap between old-school gastronomic precision and raw elemental heat. With Theo Clench - the man who essentially sprinted to a Michelin star at Cycene - now at the helm, the concept shifts away from the caveman theatrics of modern grilling. Here, the smoke hasn't cleared; it has just become infinitely more sophisticated.
The Scene
The room remains a masterclass in "Mayfair Dark": a narrow, subterranean slip of walnut, charcoal hues, and low-slung velvet that whispers rather than shouts. It is the kind of space where the lighting makes everyone look like they’ve just returned from a restorative weekend in the Maldives.
You want the counter. Watching Clench and his team navigate the hearth is like watching a ballet performed inside a volcano. There is no frantic shouting, only the quiet, rhythmic clicking of tongs and the occasional orange glow of a shifting ember.
The Alchemy
Clench operates with a striking, surgical stillness at the hearth, and at IGNI, he has clearly found his element. Fire here isn't used to dominate the plate; it is applied like a seasoning, subtle and deliberate. It is a masterclass in restraint, proving that in the right hands, a roaring hearth can be used with the precision of a scalpel rather than the blunt force of a bludgeon.
The Bread: Forget the sourdough clichés. The Yukon Gold potato bun is the star here. It arrives looking like a polished river stone, glazed in wagyu fat and miso, topped with a drift of burnt white truffle. It’s accompanied by a broth of smoked soy that is so umami-dense it feels like it might actually be sentient.
The Seafood: Drawing on his Brighton roots, Clench treats fish with a reverence usually reserved for religious icons. The Hand-dived Scallop isn't just seared; it’s kissed by the flame until the edges caramelise into a candy-like sweetness, while the center remains a cool, translucent ivory.
The "Cycene" Touch: Fans of his previous work will recognise the Tuna Sequence. It’s a triptych of fat and fire - akami, chutoro, and otoro - each cut manipulated with different smoke intensities. The chutoro paired with foie gras and shiso is a bite that justifies the entire Uber ride across town.
The Pour
The wine list is predictably "Big Boy Mayfair" - expect the heavy-hitters from Burgundy and Bordeaux - but the sommelier team is delightfully playful. Ask for the "liquid kitchen" cocktails. They use the kitchen's byproduct (think toasted brioche skins and oyster shells) to create drinks that are savory, saline, and dangerously easy to drink.
The Verdict
IGNI is the most elegant thing to happen to fire since the invention of the candle. It is a restaurant for people who want the primal thrill of the hearth without the singed eyebrows. Clench has traded the bravado of the grill for the precision of the scalpel, and the result is nothing short of magnetic.
The Details
The Order: Go for the full 8-course journey. Anything less feels like leaving the theater at intermission.
The Seat: The kitchen counter, specifically the middle seats. It’s the best theater in the W1 postcode.
The Vibe: High-fashion monkhood. Wear something black, Japanese, and expensive.
Thank you to Theo Clench and the rest of the incredible IGNI team for your hospitality.
