I'm not big on Sushi, Sashimi (or anything raw, for that matter) so I'll let the previous reviews do the talking. That's also why I don't do many reviews on Sushi / Japanese places.
But when I do go for Japanese, I tend to rate them on the quality of their non-raw selection.
My experience with Kagawa has always been courteous and gracious. I tend to go around lunch time on the weekends, and it's not too busy then. The staff were more than willing to accommodate our sometimes-larger group upwards of 10 people. Lunch in particular has a pretty good selection of bento boxes. The salad in these boxes are pretty good - typical iceberg lettuce and vegetable affairs (somewhat cold from the freezer, but no obvious freezer burns) and tangy with their dressing. Portions are fair, especially with the beef. In recent years, however, the price has gone up while the portions have remained the same.
Couple of times, the chicken was dry, and the beef chewy, but overall its well sauced. Staff are rather friendly, but can sometimes forget about you if you're in one of the hide-away booths at the end.
Now to be absolutely fair, bento boxes are no way to rate a restaurant - but my experience with this restaurant has been solely isolated to these, so take it with a grain of salt.
