A food manga about a man who travels all across Japan via train and eats every famous railway box bento along the way.
Although I have zero interest in trains I do love food so I still enjoyed this series a lot. They meticulously review every part of each bento as well. It almost feels like free advertising for these various lunches.
If I ever get back to Japan I’ll make sure to look up some of these famous bentos while traveling.
