Undercooked Pattie: Severe Illness - Five Guys, Köln Nordrhein-Westfalen

113-117 Schildergasse, Köln, 50667 Nordrhein-Westfalen, Germany

I ate at Five Guys in Cologne. I found it strange that the burger pattie was half raw. About 3 hours later, I had more extreme stomach pain than ever before in my life.
It's been 3 days since then and I'm still having brutal diarrhea and extreme stomach cramps.
The meal at Fife Guys was the only meal I ate on that day.
My conclusion: I will never eat in this shop again and I can't recommend it to anyone. Employees apparently lack the safe and hygienic handling of food. | Symptoms: Nausea, Diarrhea
