I have fallen into a very miserable situation whereby the restaurant staff have accidentally served pork along with chicken and we might have had eaten a bite or two of the food. What do I do now and is there a Kaffara?
We enquired from the staff before ordering if the food was Halal and they did confirm that it was Halal. Kindly advise. We are really disturbed after this incident. Your guidance will be deeply appreciated.

Do esteghfar from Allah
