Onzon Thai food hygiene rating
Other catering premises · Vale of Glamorgan
Onzon Thai holds a 3: generally satisfactory. The business met the legal standard, but the inspector recorded enough minor issues that it fell short of a good or very good rating.
The rating: 3 - Generally satisfactory
The rating dates from 24 September 2025, 9 months ago. Councils typically re-inspect higher-risk businesses every six months to two years, with well-run, low-risk places visited least often, so this is a normal gap.

What the inspector found
- Hygienic food handling Generally satisfactory
- Cleanliness & condition of the building Good
- How well they manage food safety Generally satisfactory
An inspection scores three things: how food is handled, the physical condition of the premises, and how much the inspector trusts management to keep standards up. At Onzon Thai none of the three raised a concern, the overall rating is only ever as strong as its weakest area, so a clean sweep is what produces a high score.
