Grubby Grub is a Chrome add-on that enhances your Google Maps experience by displaying UK Food Hygiene Ratings for restaurant listings. By simply clicking on a UK address in Google Maps, users can instantly view the Food Hygiene Rating of the establishment. The ratings are typically on a scale of 1 to 5, with Scottish businesses utilizing a Pass/Fail system instead.

This handy tool provides valuable information for users concerned about food safety and hygiene standards when dining out. With Grubby Grub, users can make more informed decisions about where to eat based on the displayed hygiene ratings directly within Google Maps.
