“This place is a very beautiful and large casino. The bartenders were very friendly and quick service. Screens of slots were dusty, and did go on a weekday but the lack of 15$ blackjack tables was shocking to me. Dealer was fun and friendly as well. The Christmas decorations are absolutely gorgeous. This time i did not stay in a room specifically because they decided to start closing the indoor pool, so i choose embassy suites now over them unfortunately....”
“What a great place ! I’ve driven by it many times visiting Saint Louis . As often as we go to Vegas , had no desire to stop/ stay. I’m so glad we did . The casino didn’t bleed you dry. The standard rooms would be considered a junior sweet elsewhere. The 18th floor had an amazing view of the city and the beautiful pool ( that I wish I was prepared to use). Water nice and hot .

“Ameristar Casino has a great, fast pace lively energy vibe. The room was cozy, clean, and the high-rise view was such a nice touch. Customer service was on point, and the food options were solid and convenient for a late night snack. The only downside was the bedding. It could definitely use an upgrade. Overall though, the room was dope and comfortable, and I’d stay again.”
