We hadn't ever visited Central City or Black Hawk so after we checked in and got our club cards, we went out to explore other casinos and Grand Z remained our favorite. The atmosphere was easy and comfortable, we got drinks fairly quickly, they have one of the bigger video blackjack table machines which was our favorite and a lot of the other places didn't have one. We redeemed our vouchers for free prime rib dinners and the food was actually pretty good. They have a deli open all night, which was great for 3am munchies. The room was clean and updated and not too hard to get to. We plan on going back and I doubt we'll ever stay anywhere else when in Central City/Black Hawk.
