Our server is a fountain of food knowledge, talking us gently through the omakase-style starter platter as dishes begin to arrive; a large oyster filled with apple-smoked celeriac purée and a refreshing jelly, a smoky sea eel custard and a skewer of satisfyingly fatty tuna pieces introduce us to the pervasive wood-fired theme.
Whole, sustainably-caught Portuguese and Spanish blue fin tuna are central to Kokin’s offering, making it one of very few places in the capital where you will find such quality and the more unusual cuts from the entire fish.
Accordingly, a real highlight is the tuna collar which arrives next, doused with an eight-year aged homemade Ponzu sauce; the fat and flesh strikingly meaty, as its rich, briny-deep flavours further ratchet up the meal’s smokiness factor.
The simple hit of a Keigetsu Nigori sake, hailing from the Kochi prefecture, works a treat alongside the slivers of expertly wood-fired wagyu sukiyaki and egg yolk (see main pic), before we’re back to three more cuts of tuna, meddled with pearly Ikura salmon roe.
This is the signature Temae Sushi dish, or ‘sushi made by me’, which has my guest grumbling that he’d much rather have his maki expertly rolled by the kitchen rather than to be fumbling about with it, but the hands-on experience definitely adds to Kokin’s crafted blend of Japanese perfectionism mixed with a more informal and relaxed dining style.
After more sake as darkness begins to fall through the windows, I really like the wood-fired ice cream finale. It rounds things off with a gentle last nod towards the kitchen’s all-important flames; the luxurious creaminess of a single scoop set against the acidic tickle of fermented raspberries which lie beneath.
The acclaimed chef behind all this, Daisuke Shimoyama, made his name introducing the artful, seasonally-focused Kaiseki style to London’s dining scene, at Hannah on the South Bank, and the floral touches and carefully plated dishes demonstrate the evolution of the lineage as it moves out East.
His new Stratford home is a sumptuous yet also quite tricky space to work with, but there’s enough talent and ingenuity in the menu, assuredly infused with the all-encompassing influences of the fire, to draw sushi-lovers back up to the 7th floor.
