The tempo from the entrance to the guidance is good, and the staff's response is very pleasant. There are many fun menu options to choose from, including sashimi, fried chicken, and katsudon. In particular, the braised pork is tender, and the melt-in-your-mouth texture is irresistible. The seasoning of the katsudon is just sweet enough, making it satisfying to eat. Miso soup and small side dishes are also included, contributing to a high overall satisfaction. The service is smooth, and there are takeout bento options available, making it convenient.

Upon entering the restaurant, you are greeted with bright smiles, making for a pleasant experience. They provide a wet towel and a teacup, and you can freely enjoy cold tea by yourself. The daily specials include a variety of dishes such as a mixed platter, sashimi, and braised pork, making it fun to choose. The pork miso soup contains daikon, lotus root, carrots, taro, bunashimeji mushrooms, and burdock, allowing you to fully appreciate the rich flavors. The fried chicken has a crispy coating and a pleasant ginger aroma, making it irresistibly delicious. Grilled fish and fried horse mackerel are also available, and the selection of sake is attractive and exciting.
