【Visit】 I visited on a Saturday at noon. I made a reservation about two months ago. There were a few walk-ins on the day, but it seemed like they were fully booked with reservations and had to turn people away. 【Food, Service, Atmosphere】 The restaurant has a charming old house vibe, with the dining area located at the end of a narrow hallway after you open the door. I was warmly welcomed with attentive service. The interior features a wooden decor, and there was no background music, allowing me to quietly enjoy the sounds of the kitchen for about 30 minutes while I waited. When the tray arrived, it was elegantly presented, and the tiered box had an impressive aura that made opening it an exciting experience. The appearance was beautiful, with a dazzling glaze. The skin was crispy and fragrant, while the meat was fluffy and tender, with a subtle smoky aroma and no bitterness at all. I had thought that eel was all about the sauce, but the sauce here did not overpower the eel at all; it truly enhanced the ingredients. The richness of the fat made my appetite grow as I saw the glistening fat at the bottom of the bowl, and I might have felt the strongest urge to say "I want more!" after finishing than ever before. Both my husband and I were extremely satisfied, and we were moved to have come all the way to Matsumoto just for Yamasei. 《Rating》 5.0 | A memorable and special place I would love to revisit this restaurant, even from afar.
