Manhattan, NY — Tomo21 Sushi, located at 172 Thompson Street in Greenwich Village, received a score of 27 following a New York City Department of Health and Mental Hygiene (DOHMH) inspection conducted on March 25, 2026. The score places the restaurant at the uppermost boundary of the Grade B range, one point below the threshold at which a Grade C is assigned. Inspection data was released by DOHMH on March 27, 2026.

What Inspectors Found

Inspectors documented two violations during the visit — one critical and one non-critical.

The critical violation, cited under Code 04N, involved the presence of filth flies or food/refuse/sewage-associated flies in the establishment's food and non-food areas. This category includes house flies, blow flies, bottle flies, flesh flies, drain flies, Phorid flies, and fruit flies. Pest activity of this type is treated as a critical violation under NYC Health Code standards due to the direct risk of food contamination.

The non-critical violation, cited under Code 10B, identified the absence or inadequacy of anti-siphonage or back-flow prevention devices where required, along with improper drainage or liquid waste disposal. Drainage deficiencies can contribute to conditions that attract pests and create sanitation concerns if left unaddressed.

Food Safety Context

Under NYC Health Code Article 81, food service establishments are required to maintain conditions that prevent pest entry and harborage, ensure proper plumbing function, and protect food from contamination. The FDA Food Code similarly identifies pest activity as a significant risk factor for foodborne illness, requiring operators to implement integrated pest management practices.

A score of 27 represents the maximum a restaurant can receive while still retaining a Grade B. The single-point margin between this result and a Grade C underscores the significance of the violations identified, particularly the critical pest-related citation, which carries a higher point value in DOHMH's scoring methodology.

Inspection History

Tomo21 Sushi has a prior inspection on record with DOHMH:

  • January 11, 2024: Score 34, Grade N (score pending grade assignment at time of inspection)

The 2024 result fell within Grade C territory. The March 2026 inspection, while an improvement over that prior record, still reflects ongoing compliance challenges at the location.

Understanding NYC Restaurant Grades

DOHMH assigns letter grades to restaurants following inspections based on the total point score:

  • A: 0–13 points (lowest violation severity)
  • B: 14–27 points
  • C: 28 or more points (highest violation severity)

Grades are required to be posted in a location visible to the public. Consumers can look up the full inspection history for any permitted food service establishment in New York City through the DOHMH restaurant inspection database at the NYC Open Data portal or via the NYC Restaurant Inspection Results search tool on the city's official website.
