This made me chuckle, found on the MyLondon site:
"A Ladbroke Grove
bakery was given the worst possible hygiene rating after an inspector
found "one of the heaviest and mouse extensive mouse infestations" they
had ever seen.
After an inspection on February 21, St Helen's Bakery was given a 0 out of 5 food hygiene rating by Kensington and Chelseacouncil, meaning that urgent improvement is required.
There is more HERE
I imagine that the mice gave it a very high rating.
