re: Worst restaurant experience you've ever had?

At prime steakhouse at bellagio. We had someone with us that had a tree nut allergy. We had called ahead and made arrangements with the managers to let them know of the allergy. When we arrived, we went over the allergy again with the waiter and he assured us the meal would be ok. First theing they bring out is bread, with walnuts. Had to hurry up and leave, and the security came to get a state,ment. Was the biggest guy I had ever seen, but was super nice. Greatest birthday dinner ever.
