Fair Menu Introduction

**Charcoal-Grilled Skipjack Tuna Tataki (Ponzu)** Skipjack tuna caught off the coast of Yaizu, Shizuoka Prefecture, which boasts the highest tuna catch volume in Japan, is expertly charcoal-grilled to a fragrant finish. It is frozen on board to preserve its freshness and has a high-quality, umami flavor without any gaminess. Enjoy it with a refreshing ponzu sauce. ¥759 (tax included)

**Charcoal-Grilled Skipjack Tuna Tataki Yukke** Using skipjack tuna from Yaizu, this dish is finished with a special sauce based on soy sauce, with the sweetness of apple and the flavors of garlic and ginger, creating a yukke-style plate. It's an addictive taste with a rich, overlapping umami. ¥649 (tax included)

**Insanity!! Garlic Soy Sauce Fried Chicken** Garlic-infused, truly "insane level" garlic soy sauce fried chicken. One bite explodes with the umami of garlic along with the richness of soy sauce, leaving an impact that blows away your reason. An irresistible dish that makes even the sense of transgression addictive. Single (3 pcs) ¥418 (tax included) Double (6 pcs) ¥825 (tax included)

**Devil!! Garlic Yakisoba** A stamina-packed yakisoba that maximizes the flavor of garlic. Stir-fried pork belly and chives, and crispy bean sprouts are mixed with the noodles, delivering a wave of umami with every bite. A dish of "devilish deliciousness" that you won't be able to stop eating once you start. ¥649 (tax included)

**Rush!! Garlic Gyoza** Crispy and fragrant on the outside, juicy on the inside. Served with a special sauce made of vinegar, black pepper, and grated garlic, it's a refreshing yet punchy flavor that will make your chopsticks and beer race. ¥495 (tax included)

**Dangerous!! Garlic Ajillo** Danger! We put too much garlic in. This dish is a hot oil infused with garlic and chili peppers, allowing the umami to slowly melt in. It's an "addictive" ajillo where you can enjoy the tender garlic and generously soak the baguette in the oil. ¥495 (tax included)
