A refined Japanese restaurant with unusually strong seafood and wood-fire cooking, but allow extra time for occasionally uneven service and budget carefully for a premium Stratford meal.
Kokin Restaurant delivers strong food quality anchored by fresh seafood and signature dishes like wagyu ramen and black cod, yet inconsistent execution across visits prevents a higher grade. Modern hotel elegance and knowledgeable service create a polished experience, though occasional lapses in attentiveness and pacing keep it from approaching grade A territory.
Kokin occupies the seventh floor of The Stratford, where warm wood, an open kitchen, natural light, and a generally calm room create a polished escape from the bustle below. Diners describe it as feeling closer to East Asia than ordinary London dining, with views and a quiet, date-friendly mood. The catch is operational: many visits are warm and attentive, but others encounter slow drinks, delayed sushi, forgotten orders, or a bill that seems to require its own reservation. The cooking is the main event. Kokin pairs fresh bluefin, sashimi, nigiri, ramen, and Japanese comfort dishes with wood-fire smoke, smoked sushi rice, eel chawanmushi, oyster katsu, and interactive hand rolls. The result is contemporary Japanese food with genuine technique rather than a standard sushi menu, and the tuna showcase dinners add a memorable performance element. Lunch sets and ramen are the cleverer value plays; premium nigiri, wagyu, lobster, and event menus push the bill firmly into treat territory. Families can manage here, especially at lunch: the menu includes chicken, rice, ramen, fried chicken, vegetable tempura, mochi, and several vegetarian or vegan choices, and one diner enjoyed lunch with a baby. It is not a conventional kids' restaurant, however, and much of the menu centers on raw seafood, strong umami, eel, roe, and adventurous preparations. Picky eaters may be happier with chicken ramen, rice, karaage, or vegetable tempura than with the chef's selections.

Fresh bluefin, smoked wagyu nigiri, black cod, and wagyu ramen are among the strongest choices, with theatrical tuna experiences available for a higher spend.
Kokin is polished but expensive and occasionally slow, with bold raw-seafood-focused cooking and bills that can rise quickly with drinks or premium dishes.
A warm, light-filled seventh-floor room and open kitchen give Kokin a calm date-night feel, with interactive sushi experiences adding a distinctive edge.
