Kanpai Classic Soho: A Wagyu-Fuelled Symphony of Smoke, Style and Sublime Flavour

Wardour Street does not lack for spectacle. Neon flickers, restaurant windows glow and Soho hums at its usual pitch. Kanpai Classic Soho answers all that noise with a dark, softly lit room and a quiet promise: the best beef you will eat this year, cooked right in front of you. It calls itself a “new-style Japanese steakhouse”, a phrase that sounds like marketing until the first slice of Wagyu meets the grill. After that, it sounds more like a warning.

The story begins in Taiwan in 1999, when mobile phones still had antennae and Wagyu was a word known mostly to serious beef obsessives. In the quarter-century since, Kanpai Group has refined its Yakiniku craft, rising from night-market beginnings to Michelin-level acclaim, with its Shanghai restaurant credited as the first Yakiniku venue to win a Michelin star. London now gets the benefit of all that practice, and the debut is a confident one.

Picture a Kyoto grill master with a Le Cordon Bleu education, an obsessive butcher and a designer with a weakness for shadow, all agreeing on a single brief. That is the energy of the room: hushed, expensive and just a little smug about it, in the nicest possible way.

Grilling happens at the table, as Yakiniku tradition demands, and each cut is handled with the reverence usually reserved for vintage wine. The kitchen doesn’t merely serve steak; it curates it. There is the Miyazaki “Himawari” Wagyu, chosen through an exacting two-step grading process, and the rarer Moriawase cuts, each arriving marbled like polished stone and waiting politely for your full attention.

Our guide was Faye, a server with the calm authority of someone who has explained fat to the uninitiated many times without once raising her voice. She walked us through each cut’s origin, its ideal grilling technique and its flavour profile. There is a particular pressure in being handed tongs over A5 beef while an expert watches, and she managed it graciously, stepping in only when we began to hover.

We opened with Schrenckii Dauricus caviar, briny and nutty, set against a chilled Charles Heidsieck Brut Réserve. Think tuxedo and evening gown: timeless, and perfectly complementary.

Then came the main event, six cuts of premium A5 Himawari and Moriawase. The Karubi was meltingly tender. The Picanha offered a satisfying chew and deep umami. The Oyster Blade stole the round, gently sweet with a whisper of smoke. Each piece met the flame for mere seconds per side, timed with a conductor’s precision. Faye explained why one fat needs a flash of heat while another prefers patience, and how best to taste each: with a pinch of salt, a light dip in the house condiments or, occasionally, naked and unadorned.

Taken together, the selection made the case for the whole animal, not just the showy sirloins and ribeyes that dominate Western steakhouses, but the subtler, more characterful cuts that rarely get their moment. Many upscale menus feel like an arms race of extravagance. Here the aim stays refreshingly clear: respect the craft, honour the cow and let the beef do the talking. Thanks to careful pacing and sensible portions, it felt like a guided tasting rather than a meat marathon, though our belts requested a loosening by the third round.

Between grills came small plates, each good enough to headline elsewhere. The Wagyu truffle tallow chips were the sort of thing you find yourself thinking about the next morning. The spring rolls and gyozas, crisp and pillowy respectively, each carried a deep savoury richness. Best of all was the Wagyu temaki, a hand roll of Kobujime salmon and roe that delivered brine, fat and fragrance in a single bite. Pretty enough to photograph, and gone before anyone did.

For a gentle reset, the chicken Kamameshi arrived: Hokkaido Nanatsuboshi rice with a comforting bonito broth, homely and quietly soulful. Then a sample of the signature Wagyu curry, velvety and aromatic, rich enough to justify a return visit all on its own.

Dessert, improbably, was no afterthought. The soufflé cheesecake was creamy and indulgent, while the chocolate fondant was gooey without turning cloying. Alongside came two cocktails, the Blossom and the Green Tea Geisha, both gently floral and bright enough to cut through the richness without stealing the show.

One minor quibble: the wine pairings could use more depth and guidance. With Wagyu this nuanced, the right red or a thoughtful sake could unlock another level entirely. A small thing to finesse in an otherwise assured offering.

Kanpai Classic Soho manages something rare, a serious devotion to ingredient and craft delivered without a trace of stuffiness. It is a steakhouse, yes, but one that reinterprets Eastern technique for a Western audience and reminds us that, in the right hands, meat, flame and salt can still astonish.

So if you find yourself in Soho and in the mood for something special, skip the predictable pasta and the standard sushi. Come prepared to savour, sip and sizzle. And maybe don’t plan anything energetic afterwards.
