I'm going to revise my original post after going on the maricopa.gov restaurant inspection list. It appears Shimogamo has a few citations for not keeping their fish at the appropriate temperature of below 41 degrees. In fact, these citations say it was up to 54 degrees.
As someone who checks the Maricopa.gov site regularly on these restaurant checks, I know that there are some citations that are really stupid (for example - they got cited for not putting the "consuming raw fish etc is bad for your health". Duh, it's a sushi restaurant. But, raw fish storage to me is important, since that's how many people get sick from sushi restaurants. As much as I liked this place, I am going to hold off a couple months until the next inspection to make sure this isn't re-occuring .
