Really not impressed. At all.
I judge a Japanese restaurant by their katsudon. In this case, it was really "ma ma"--"not so good" in Nihongo (Japanese). As a matter of fact, I quit eating it after the second bite and ordered a tonkotsu ramen.
This was definitely not a traditional katsudon. Instead of a sliced katsu, steeped in shoyu sauce base with cooked mixed egg and onion slices on top of rice, it was sort of chunks of katsu with sort of egg mixed in with large chopped pieces of onion sort of mixed in with rice--and no shoyu-based sauce. Very dry. Not appetizing. And the katsu was over-cooked and somewhat tough. I would give this katsudon only 1.5 stars.
The ramen was better. Decent broth, decent ingredients. However, there was way too much bean sprouts in it which totally got in the way of enjoying the noodles. I really didn't like it being served in a paper cup/bowl, either. I would give the ramen 3 stars.
I had a bite of my wife's yakisoba. It was OK, not great. Maybe 2.5 or 3 stars.
Service was very friendly. I do not think he is Nihonjin, though or else he really does not know the language because the little Japanese I spoke to him in Japanese tradition, he kind of mumbles something inaudible back.
