Bad food served at Ghazal Indian restaurant

Me & my wife like biryani, so we thought of dinning at the Ghazal Indian restaurant in Sunninghill. We ordered for vegetable biryani. Ate three s****s of biryani and my stomach bloated badly. Felt a strong pain in my intestine like its been clamped. My wife also felt the same way, so we were sure that something was wrong with the biryani. We stopped eating, payed the bill and rushed back to home. Took medication to get rid of the pain. What poisonous adulterants do you put in the food that you make? Never will I go to that restaurant again :(
