The sashimi is fresh, cold, and excellent quality. Yes, it's a little more expensive than the grocery store. However, Kobe is well worth it if you have the discriminating palate to appreciate the quality. They had (at the time) fresh scallops still in the shell. pretty expensive, but the sushi chef let me hold the shell and show my boy the "before" state of our meal.
Service is good, but if you go to a *real* sushi restaurant, you have to accept a certain level of language barrier. Communicate clearly and adapt or go to McDonald's.
