i've been to new japan and i wasn't too impressed, but i do like that they are open late. as far as famima is concerned, i should have mentioned that i am looking for a place with tables, but i will give it a try sometime.
I don't think they have katsu on their menu, but Saks in Westwood has a great terriyaki! There is dark meat and white meat options. Saks brings back such fond memories at UCLA as a student when you're poor and hungry!
