Cooked plastic in my food

The overall experience at the restaurant was poor, with flies doing thier rounds on the tables. I ordered a mutton burger, 1/4 way through I realised that I am chewing on plastic. They kitchen staff literally fried the burger with the plastic on it. The restaurant staff were less than apo⁹logetic about about the incident, simply took the burger away and said nothing. I certainly will never recommend this place to anyone. Terrible service and the food leaves little to be desired.
