Z Casino is quickly becoming the place to play in Blackhawk. Every time I visit there are new machines, they play good music and their prime rib is delicious. I haven't hit anything over $300 here, but I consistently win smaller amounts, which makes it fun and keeps me coming back. I have encountered a few rude/unfriendly staff members at the player's club desk, but the rest of the staff makes up for the few rude ones. That's the only reason I gave them 4 stars, otherwise they're awesome!
