Manhattan, NY — Jackson Hole, the hamburger restaurant at 521 Third Avenue in Murray Hill, received a Grade B following a health inspection conducted March 31, 2026. The New York City Department of Health and Mental Hygiene recorded a score of 25, placing the restaurant near the upper boundary of the B range and just three points below the Grade C threshold. Inspection data was released by DOHMH on April 2, 2026.

What Inspectors Found

Inspectors documented one non-critical violation during the March visit:

  • Code 10F: A non-food contact surface or equipment was found to be made of unacceptable material, not kept clean, or not properly sealed, raised, spaced, or movable to allow accessibility for cleaning on all sides, above, and underneath the unit.

No critical violations were cited. While the single violation is classified as non-critical, the weight assigned to it under the DOHMH scoring system was sufficient to push the overall score to 25 — one of the higher totals within the Grade B band.

Food Safety Context

Under NYC Health Code Article 81, restaurants are required to maintain all equipment and surfaces in a sanitary condition and in good repair. Non-food contact surfaces — such as the exteriors of equipment, shelving, and structural components — must be accessible for routine cleaning to prevent the buildup of grease, debris, and conditions that could attract pests or allow bacterial growth.

The FDA Food Code similarly identifies equipment design and maintenance as foundational to a safe food service environment. While non-critical violations do not indicate an immediate public health hazard, they reflect conditions that, if left unaddressed, can contribute to more serious sanitary deficiencies over time.

A score of 25 falls within the Grade B band but sits at the higher end of that range. By comparison, a score of 28 or above results in a Grade C posting.

Inspection History

Jackson Hole's recent inspection record shows variability in scores over the past several years:

  • November 19, 2025: Score 40
  • August 15, 2024: Score 13 (Grade A)
  • December 20, 2023: Score 30
  • November 22, 2022: Score 13 (Grade A)

The restaurant earned Grade A scores in both 2022 and 2024, but recorded scores of 30 and 40 in back-to-back inspections in late 2023 and late 2025. The current score of 25, while an improvement over the two prior results, continues a pattern of inconsistency.

Understanding NYC Restaurant Grades

New York City requires restaurants to post their most recent letter grade, determined by the score assigned during DOHMH inspections:

  • Grade A: Score of 0 to 13 points
  • Grade B: Score of 14 to 27 points
  • Grade C: Score of 28 points or more

Lower scores reflect fewer or less severe violations. Restaurants that score above 13 on an initial inspection are re-inspected before a grade is officially posted.

Inspection records for all New York City restaurants are publicly available through the DOHMH Restaurant Inspection Results database at the NYC Open Data portal.
