Because I was on a business trip I figured I would treat myself to the steak house they have on the property and dined at 650 Park. During the time I was there I did NOT see ANYBODY win a jackpot of any size. I was there for almost 3 hours, the first hour spent walking around familiarizing myself with the grounds, and the majority of the machines were all identical, offering a few different versions of the same gambling games. Although the size of Graton definitely has them beat, this casino is in no way better than the casinos located in northern California.
I'm from Sacramento and frequent Thunder Valley Casino and Cache Creek, among others. Stopped there for dinner and a little gambling on a Thursday evening, just a week after they opened.
