Mediocre, really.
Ordered a lunch special - a don katsu bento box - and was thoroughly tired of it only a few minutes in. The don katsu itself was very dry. The sushi was very bland. The tempura, while decent, was ruined by the tempura sauce which had a distinct sweet taste reminiscent of Chinese medicine.
Overall, the food looked like the atmosphere and the servers - namely that of blandness, boringness, and lingering hope for something a bit better.
