From a Japanese international travel guide:
10610 W Pico Blvd, Los Angeles, CA 90025
The place, where it is, is far from downtown LA. The store, or lunch house, stays because it is making confusion. Considered from outside you do not understand at all. In the store, which it appeared to be, you are surprised by tasty kind of meat which is the meat eaten only in Japan. The storekeeper to the last has only done business with word-of-mouth communication, no advertisement having been done. It is a very good place, known to very few people.
If you go to the LA please try going, by all means.
