Restaurants in London have been highlighted by figures from the Food Standards Agency (FSA) as needing improvement with one in five being warned by inspectors.
The FSA found 3112 restaurants in the capital in need of food hygiene improvement and 1729 were given a rating of 1 or 0 by the agency.
The capital is well below the rest of the country with twice the average number of restaurants being warned by inspectors.
The survey by the FSA found that although 39% of those polled reported having a bad experience when eating out, 41% never check the ratings before choosing a venue.
Catriona Stewart, head of the Food Hygiene Ratings Scheme, said: “91% of restaurants are rated 3 and above. We hope this survey will encourage those restaurants that have a low rating to improve their food hygiene practices.”
