Towers record on food hygiene was not brilliant. Remember the inspection is only a "spot check" on one particular day, if standards are good on that day then you're OK. Just search your local paper and you'll find a report of a place going from a 5 rating down to a 1 - the manager / owner will always wheel out the "this was an oversight / someone was on holiday" type of excuse.By improvements do you mean in terms of hygiene or quality?
Food hygiene reports do not take into account food quality, therefore fast food takeaways can still get a 5.
In terms of hygiene it's probably better that they get it right first time but if they get a low score it can be six months before the next inspection.

Remember Ripsaw Cafe? There was a portakabin out the back of it used as a store-room. It had fungus growing in the floor. Said portakabin had been used as a staff "green room" and was shut down because of the fungus - of course, the reason given for closing the green room was that Air construction had finished & there were two "shiny new" [portakabin] green rooms behind the Air-gates.
