I’ve got a buddy who is a salesman for a food supplier.
He has some great intel on local restaurants, and as you say, you can’t always tell by the serving side of the operation.
It would be nice to have inside info on restaurants cleanliness.
I know a guy who runs a huge food service which serves several thousand people at a time tho usually it is not that many. I can remember when that place used to have a case of food poisoning about once a Summer. The food was great but the cooks were not very clean.
After this guy took over, there was never another case. He was a fanatic about cleanliness.
