When you are in Matsumoto, never miss a chance to try this infamous Unagi (eel) restaurant just a few minutes from the station. Reservation is not allowed and seats are limited till they run out of Unagi for the day. It’s not cheap but it’s definitely worth it.
Customers usually starts lining up outside the restaurant as early as 11:00 or before that just to get a seat. Y and I were very lucky to get one for ourselves and had a great time having our Unagi bowl with rice.
