Gyokai Zanmai Genya (魚貝三昧 げん屋) is a seafood-focused izakaya in Toyohashi that elevates dinner to a performance. The experience often begins with the chef presenting a 'Tamatebako'—a treasure box of the day's fresh ingredients—and centers on dramatic, high-quality preparations. The restaurant is particularly famous for its live aori-ika (bigfin reef squid), which is prepared as sashimi at the counter, and its warayaki katsuo, bonito seared over a roaring straw fire.

Guests consistently praise the freshness and variety of the seafood. The signature aori-ika sashimi, with its tentacles later served as tempura, is a highlight. Another unique offering is the ikawata, or grilled squid liver, which is used to create a rich fried rice dish to finish the meal. Other popular items include large grilled clams and elaborate sashimi platters featuring uni (sea urchin) and rare local fish like ku-e (longtooth grouper). The chef's omakase courses are a popular way to experience the best of the kitchen's offerings.

The main criticism is the price; reviewers note that it is expensive, though most feel the quality of the ingredients, the skillful cooking, and the excellent sake selection justify the cost. A few isolated comments mention service feeling rushed on busy nights or certain live seafood items being sold out later in the evening.

Expect to spend around ¥8,000–¥10,000 for lunch and ¥10,000–¥15,000 for dinner. Reviewers have recently paid between ¥8,800 and ¥16,500 for various chef's omakase courses. A la carte, a whole live aori-ika was noted at around ¥8,000, and a pair of large oysters at ¥2,000.
