About Koki
Tucked beneath Capella Hanoi in the French Quarter, Koki brings Michelin-starred Japanese precision to Vietnam through three distinct experiences: Hibana's intimate 14-seat teppanyaki counter, the Michelin Selected Izakaya, and a pristine sushi bar. Ingredients fly in twice weekly from Japan—premium seafood, Yaeyama Kyori beef, and the raw materials that allow chef Hiroshi Yamaguchi to practice the exacting standards he honed at Tokyo's acclaimed Ishigaki Yoshida. The name means 'bright and shiny,' a nod to the cheerful mastery behind the iron griddle, and the sake program stands as Vietnam's most extensive, with nearly 60 labels to explore.
Good to know
Book Hibana's teppanyaki counter for the full theatrical experience, but don't overlook Izakaya if you want to explore more dishes at a gentler price point—the Michelin Selected à la carte menu shares the same kitchen pedigree.
The chef
Hiroshi Yamaguchi
Hiroshi Yamaguchi built his reputation in top-tier kitchens across Japan and internationally, with a formative stint at Ishigaki Yoshida in Tokyo, where he absorbed the discipline and precision that define high-level teppanyaki. His approach centers on ingredient purity—sourcing premium Yaeyama Kyori beef and twice-weekly seafood shipments from Japan to ensure nothing compromises the raw materials. At Koki, he's translated Tokyo's exacting standards to Hanoi, creating a teppanyaki experience that respects tradition while adapting to a Vietnamese audience eager for Japanese authenticity. His cheerful demeanor at the counter—the 'bright and shiny' spirit the restaurant's name evokes—makes the technical mastery feel approachable rather than austere.
The Insider Compass
Four dimensions, each assessed independently against the same criteria everywhere we rate.
Plate
Yamaguchi-san's teppanyaki technique is theater backed by substance—Wagyu beef seared to precise doneness, tempura with a delicate batter, and miso black cod that balances sweet, salty, and umami with surgical precision. The sashimi benefits from Japan's best fish markets, flown in mid-week to guarantee pristine quality, while dishes like chawanmushi with crab showcase traditional refinement. Expect a structured progression of flavors at Hibana, though the Izakaya side offers more playful izakaya-style exploration, including an exceptional unagi don that regulars swear by.
Vibe
IntimateHibana's counter creates an intimate, focused energy where conversation flows between chef and diner, the sizzle of the griddle providing a rhythmic soundtrack. The Izakaya side carries a more relaxed, convivial atmosphere suited to leisurely sake exploration and shared plates, attracting a younger, internationally minded crowd. The basement location in a luxury hotel lends polish and quiet sophistication—this isn't a boisterous izakaya, but a refined interpretation.
Service
The brigade operates with Japanese hospitality at its core—attentive without hovering, knowledgeable about provenance and technique, and genuinely warm in their approach. Expect detailed explanations of each course at the teppanyaki counter, while the sommelier navigates the sake selection with skill, matching profiles to your palate preferences. Special occasions receive thoughtful touches—complimentary desserts, bespoke cocktails—that feel genuine rather than scripted.
Setting
The basement location beneath Capella Hanoi trades natural light for intimacy, with dark wood, ambient lighting, and the gleaming teppanyaki counter as the focal point at Hibana. Akio Bar & Lounge provides a transition space for aperitifs or post-dinner digestifs, while the overall aesthetic balances French Quarter colonial elegance with Japanese minimalism. The design asks you to slow down and focus—this is a space built for ritual, not rush.
These four dimensions are a handful of the attributes we review. The Insider Rating also draws on research the compass does not display — among them the wine programme, the size and quality of the cellar, the location, and how long the house has operated. It is not an average of the scores above.
Go for
- Vietnam's most credentialed Japanese fine dining, with a Michelin star backing the precision
- Watching Chef Yamaguchi work the teppanyaki counter with theatrical mastery and exacting technique
- The country's deepest sake cellar, offering an education in Japanese brewing rarely found outside Tokyo
Don't go for
- Casual, quick meals—the experience demands time and presence, especially at Hibana
- Budget-conscious dining—ingredients flown from Japan twice weekly command premium pricing that may feel steep even by Michelin standards
