Buffet Illness: Severe Symptoms - Buffet, Bruxelles Bruxelles

32 Rue du Marché aux Poulets, Bruxelles, 1000 Bruxelles, Belgium

We (two people including me) took the buffet menu 26 euro something which includes Beef tepanyaki, Sashimi, Sushi, and Assorted foods. We spent 2 hours there, it went well until we were on our way back home. At first, I thought I just ate too much but no, I puked 6 times, and had severe diarrhea, to an extent that I dropped my junk in the bed. What can I do about it? I only have the receipt on my bank account. Oh yeah, they didn’t even give us the receipt. | Symptoms: Nausea, Diarrhea, Vomiting
