Score
Low Risk

Public records show 13 inspections at Nano Sushi stretching back to 2010. The most recent report on file is from Oct 20, 2025. Low risk means the most recent visit produced few or no significant findings.

There hasn't been much movement either way: counts have stayed near three violations per visit across recent inspections.

“Walls, ceilings, attached equipment constructed per code” accounts for the largest share of issues, appearing seven times across the record.

That puts the facility ahead of the local pack: the average Chicago restaurant scores 81. There isn't much in the file that would give a customer pause.
