Tabelog ratingBon.nu is the singular vision of owner-chef Kei Kurusu, a restaurant in Yoyogi dedicated to an ingredient-first philosophy. The experience is defined by two signature techniques. The first is 'Bon.nu-yaki' (ボニュ焼き), a six-hour, low-temperature grilling method used on exceptionally rare Japanese beef from heritage cattle like Mishima and Tsurukusa. The second is 'chushutsu' (抽出), or 'extraction' broths, where an ingredient like lobster or ayu fish is rendered into a pure essence using only water and salt, capturing its unadulterated aroma.
Guests consistently praise the results of this minimalist approach. Standout dishes include a shiitake risotto made with just rice, mushrooms, oil, and salt; the intense lobster 'extraction' bisque; a simple yet profound soil-baked potato; and a pasta that utilizes the entire tomato, including its stem and green parts. The milk-based desserts are also a highlight. Many international visitors note that the wine pairing, selected from a Burgundy-heavy cellar, and the owner's detailed explanations are integral parts of the meal.
However, the style is polarizing. The minimal seasoning and small, intensely focused portions can leave some diners wanting more. The final bill is a recurring point of concern, as adding a wine pairing can dramatically increase the cost. A few reviewers have also reported uneven or brusque service, and there have been isolated reports of post-meal illness.
The standard omakase course costs around ¥43,000, according to recent reviews. A specific course featuring Mishima beef was quoted at ¥24,800. Diners have recently paid ¥2,980 for a potato purée, ¥6,800 for a glass of red wine, and ¥400 for mineral water. With wine, the total for two can easily reach ¥60,000 to over ¥150,000. For those seeking a unique, idea-driven tasting menu that cannot be found elsewhere, Bon.nu offers profound value. It is less suited for those expecting conventional luxury, large portions, or a predictable bill.
