I took my son to lunch at Osaka and we used a Groupon. I loved the atmosphere and the waitress was very attentive. My son had never tried raw fish before - he had only eaten California rolls, and he agreed to try it. The food was delicious, and between the two of us, we had enough California roll plus other things for him to try. He even tried the sashimi. I was not so sure about the neighborhood, but the quality of the food, the service and the atmosphere was consistent with what I have experienced in other locations.
