Food was greasy and cold, passable at best even if it was warm. My beverage was flat, and had an off taste to it, like they were using old syrup. When I sent it back and asked for water instead, the waiter tried to give my partially drank soda to another member of my party as a refill. ABSOULUTELY UNACCEPTABLE!
