I frequent Sushi Bon at least once a month. Their rolls are consistently good and fresh. Try the arctic roll; those things are like crack!
I only give it 4 stars because of the lack of professionalism of the staff. More than a few times we arrived at lunch at 12 pm only to find no one at the restaurant! (it opens for lunch at 12) I could see if they were running a bit late opening, but no one was even in the building. This happened to us about 3-4 times. Not to mention half the staff are swearing sweatpants? Very unprofessional.
If you don't mind being served by someone who obviously doesn't care about your job, the sushi is worth it.
