Review for Ameristar Casino - St. Charles Review For Ameristar Casino - St. Charles Google User Jul 20 '13 at 19:56 Do NOT eat at the Falcon Diner in the Ameristar Casino. The food is overpriced and BAD! Hash browns were so greasy I couldn't even taste the potato - only grease. Husband liked his oatmeal though. The casino reminds me of the Vegas casinos.
