I have been shopping at Costco in Summerlin for nearly fourteen years and enjoy shopping here.  I have eaten at the food court on a dozen or so occasions.  This past Thursday night at closing (8:30pm) I ordered a hot dog and added mustard and onions.  I was on my back for the next three days with food poisoning.  I went to Urgent Care late Friday afternoon because I was so sick and was prescribed an antibiotic that is given to people with Anthrax along with an anti-nausea medication.  This is day four and I'm finally able to get up and get around, although I am still weak and tired.  I will never again eat at the Costco Food Court in Summerlin (west Las Vegas).
