It's a small shop, but it's very relaxing. The master also has a calm and gentle atmosphere, but above all, the regulars are friendly and fun. Whether you go there for the first time or by yourself, you can enjoy it without feeling isolated. Recommended to go on weekends.
It is a cozy shop where a gentle master welcomes you. I think it's also attractive to have a good relationship with customers and have fun. It is convenient to be near the station.
