Food Safety Reports: Tin Cup Bar & Grille, Northeast Otter Creek Drive, Ankeny, IA, USA

I ordered an Italian burger with onion rings and my friend ordered a Pork tenderloin with onion rings for dinner. The food all tasted great, but around 1am we both woke up with stomach cramps and diarrhea. Perhaps some cross-contamination in the kitchen or bad onions?  | Symptoms: Diarrhea, Cramps
