Grosvenor Casino Portsmouth Gunwharf Quays food hygiene rating

The rating: 5 - Very good

What the inspector found

• Hygienic food handling Very good
• Cleanliness & condition of the building Good
• 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 Grosvenor Casino Portsmouth Gunwharf Quays 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.

Understanding this rating

• What does a 0 food hygiene rating mean? A 0 means the inspector found serious problems and urgent improvement is necessary. It is the lowest rating the scheme gives, but it is not a closure order, and a business with a 0 can, and usually does, keep trading while it puts things right.
• Does a low hygiene rating mean the food is unsafe? A low rating tells you that an inspector found problems on a particular day. It is not a measurement of the food, it is not a prediction, and it is not a verdict on whether you will get ill. It is the best single signal a member of the public has, and it is a snapshot.
• Does a business have to display its hygiene rating? It depends where you are. In Wales and Northern Ireland a food business must display its rating where you can read it before you go in. In England it is voluntary, a business there can legally show you nothing.
