Swensen's Restaurants @ Bugis Junction

I had lunch at this restaurant with some friends on Sunday, 14th Oct 2012. I ordered Grilled Fish with sambal and Yummy Resin scoop of icecream as dessert. The fish tasted a little underdone. Also th raisins in the icecream had a fermented taste, suggesting these were in the icecream for a long while.
By late evening I started developing some pain in the tummy followed by loose motion. By Monday morning the symptoms worsened. As I was travelling to India on Monday evening, I did not want to consult a doctor who would not be able to follow through the treatment. I reached Cochin (India) this morning and the symptoms continued. This evening (Tuesday) I consulted a doctor here who advised me to start Norflox TZ and Omez D ( the latter to preempt any nausea and other discomfort from Norflox TZ.
I Had been enjoying Swensen's icecream whenever I was in Singapore but this was the first time I tried their meal. I would request the restaurant to investigate. My friend who had different main courses and desserts did not have any symptoms.
