Worst dirty seafood place ever

I was at John dory's westgate. The oil the made our food with was dirty and black. I notified the manager who said she's aware and that it's unfortunate for is. She then forced to give us their nasty ice cream that's from a tub and tastes days old. I declined and told her I've had it and not about to repeat the experience. Serving customers food made with dirty oil worst being sea food is the worst. U will give us food poisoning and endangering our lives
