This Japanese grill yakiniku was so good that I went two nights in a row. That and I'd run out of specific Japanese food options I particularly wanted to try in Shinjuku east (I'd basically already had a ramen, an udon, a kaitenzushi, a sushi bar, tempura and then the grill).
There are lots of types of meats with focus on beef kalbiwith various marbling grades. All in all an excellent dirty dining experience.
