Thanks for pointing out my mistake, I have corrected this to be amenity=fast_food as I see this is the conventional usage. The shop is present in FHRS data (https://ratings.food.gov.uk/api/open-data-files/FHRS293en-GB.xml), and I've included the FHRS ids as described here: https://wiki.openstreetmap.org/wiki/UK_Food_Hygiene_Rating_Scheme
