Food Safety Reports: Subway, Kilburn High Road, London, UK

I bought it and Shortly after eating it the next morning I started experiencing symptoms of nausea, vomiting, dihorrea along with hot flashes!
I believe it was the subway I ate because my friend who I ate it with also experienced the same symptoms but excluding the hot flashes.  | Symptoms: Nausea, Diarrhea, Vomiting
