Review for Ameristar Casino Resort Spa Black Hawk Review For River Rock Casino Google User Jan 4 '18 at 2:26 The hotel itself is great but I was EXTREMELY disappointed that the bar inside the casino was removed. The fun atmosphere of the casino is now nonexistent. The space appears to be yet another room for high rollers. River Rock is great if you want to be close to the airport. However, if you're looking to have fun, check your other options. View full site to comment or like
