Koishii food hygiene rating
Restaurant/Cafe/Canteen · Plymouth City
Koishii holds a 4, meaning hygiene standards at the restaurant are good. It is a solid result, the inspector found nothing serious, though a 5 was just out of reach.
The rating: 4 - Good
The rating dates from 17 December 2025, 6 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 Good
- Cleanliness & condition of the building Generally satisfactory
- How well they manage food safety Good
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 Koishii 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.
