My most memorable meat meal was a Katsu combo at a restaurant called Mai Sen inside the Daimaru department store in Tokyo.
I was a walk-in in the mid-afternoon. The restaurant, which is small, was full.
I had wanted to try a special gyukatsu restaurant in Shinobu (which also has locations in Kyoto and a few other places) , called Gyukatsu Motomura, that a chef who is a friend had recommended, but it didn’t work out.
