It's one of Cardiff's most famous streets, full of bars and restaurants bustling with customers every day of the week.
St Mary Street runs right through the capital and is often the go-to place on a night out for a couple drinks or a bite to eat.
With so much choice it's often tricky to pick which establishment to go to, but one factor that might help could be their food hygiene ratings.
We've gone through every business on St Mary Street to see what their latest score is.
This is how ratings are decided:
What's taken into account when judging a hygiene rating?
- How hygienically the food is handled - how it is prepared, cooked, re-heated, cooled and stored
- The condition of the building - cleanliness, layout, ventilation and other facilities
- How the business manages and records what it does to make sure food is safe
If a business is given a zero food hygiene rating, it means urgent improvement is necessary. If it's given a five rating, the highest, it means hygiene standards are "very good".
We also checked out all the food hygiene ratings on another of the capital's famous streets, City Road, and you find out more on those here .
