San Carlo UK

We ate in the Manchester airport restaurant on Sunday 5th nov table booked at 7 , we had eaten nothing at all before here and nothing after , we flew to Mexico and both came down with extremely bad food poisoning (we seeked medical advice in Mexico) and was told it was food poisoning I was very sick and very bad tummy and hubby was also sick with tummy pains , our son did not eat the same meal as us so he was fine , we had oysters and king prawns these would have definitely be the cause of it , its ruined the first 2 days of our holiday, I know I cant physically prove it was from here but I know it was , please advise many thanks
